The ESP32-C3-0.42LCD is an ESP32 C3 / RP2040 Raspberry Pi Pico Development board with 0.42 inch LCD risc-v WiFi Bluetooth.
ESP32-C3 is a low-cost microcontroller from Espressif that supports 2.4 GHz Wi-Fi and Bluetooth® Low Energy ( Bluetooth 5 (LE)).Use RISC V as the core. There’s a minimum number of pins on this chip, it’s specifically designed to be low cost and for simpler projects than ESP32-Sx or ESP32 classics with their large number of GPIO. Think of it more as an intended replacement to the ESP8266 than to the ESP32! It has built-inUSB-to-Serial, but not native USB - it cannot act as a keyboard or disk drive. The chip used here has 4MB of Flash memory, 400 KB of SRAM.
The ESP32-C3 integrates a rich set of peripherals, ranging from UART, I2C, I2S, remote control peripheral, LED PWM controller, general DMA controller, TWAI controller, USB Serial/JTAG controller, temperature sensor, and ADC. It also includes SPI, Dual SPI, and Quad SPI interfaces. There is no DAC or native capacitive touch.
With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.
Specifications
The 0xCB Gemini is our Waveshare RP2040-Zero compatible microcontroller. It includes all the features of it’s bigger brother, the 0xCB Helios, in a much smaller form factor.
The 0xCB Helios is our Elite-C compatible MicroController, based on the high-performance and affordable RP2040.
It’s a drop-in replacement for legacy ProMicro boards.
The Frood is a high-performance and affordable drop-in replacement for the Pro Micro (used in many DIY custom mechanical keyboard kits), based on the Raspberry Pi RP2040. It is physically and electrically compatible with Elite-C/nice!nano as much as possible.
It follows the SparkFun Pro Micro RP2040 pinout with 5 extra pins (GPIO12-GPIO16) added along the bottom edge (like Elite-C), and USB data lines broken out in the top corners (like nice!nano).
The Commander is a handheld button and LED board supplied with the UF2 bootloader and CircuitPython.
The RP2040 Interfacer is designed to plug straight into your comptuer/SBC/etc. allowing quick access to UART and I2C interfaces.
The USB Interposer is a compact RP2040 based board with USB Type-A plug and socket for Meddler-in-the-Middle manipulation.
The ADM_52840 is a Breakout board to test an NRF52840 module from HolyIOT. Nothing very difficult, apart from the soldering part which requires a stencil in order to solder all the pads of the module. However, since internal pads are routed using vias, it’s possible to solder them all with a good soldering iron. It requires a J-link type programmer. An ST-Link V2 should be suitable or the J-Link of Nordic DK boards.
Seeed Studio XIAO nRF52840 (Sense) has equipped a powerful Nordic nRF52840 MCU which is designed in a Bluetooth 5.0 module, built around 32-bit ARM® Cortex™-M4 CPU with Floating-Point Unit(FPU) operating at 64Mhz. With the capabilities of wireless connection, it still remains the Seeed Studio XIAO series classic form-factor of small and exquisite which can be used for wearable devices and Internet of Things projects. Furthermore, it only costs 5 μA in the deep sleep model and it supports battery charge management because of the BQ25101 chip.
In addition, the SENSE version of the board carries two extra onboard sensors. One of them is a digital microphone created through Pulse Density Modulation(PDM) module on the nRF52840 chip. It can receive audio data in real-time which allows it can be used for audio recognition. The board can receive audio data through the MSM261D3526H1CPM microphone. The other one is 6-axis Inertial Measurement Unit(IMU) which can be applied in TinyML projects like gesture recognition. These onboard sensors provide a great convenience for users and the ultra-small size feature of the board has still remained.
The same CircuitPython firmware can be used both for the Seed Studio XIAO nRF52840 with or without additional sensor.
Seeed Studio XIAO nRF52840 (Sense) contains a wealthy interface. The first thing to note is that the Near Field Communication(NFC) is functional on the board. Secondly, there is a tiny and elegant reset button on one side of the Type-C interface. On the other side, it is designed in a three-in-one LED along with a power LED. There are 11 digital i/o that can be used as PWM pins and 6 analog i/o that can be used as ADC pins. It supports UART, IIC, and SPI all three common serial ports. Same as Seeed Studio XIAO RP2040, it has an onboard 2 MB flash which means it can also be programmed by Arduino, MicroPython, CircuitPython, or other program languages.
Why buy an Apple watch when you can spend your weekends building a microcontroller based “smart” watch instead? The TG-Watch is an open source, not-dumb watch meant for makers who want to hack on their watch, people who want to bring Python with them everywhere, or as a great starting point to learn about programming.

Meet the Pendrive S3, a device that pretends to be a keyboard, bombarding the computer with hundreds of keystrokes per second—far faster than any human could type. By utilizing a straightforward scripting language, you can program the Pendrive S3 to execute any commands you want.
Now, take this concept to the next level with the Super WiFi Duck. This innovative tool lets you manage all your scripts wirelessly through a user-friendly web interface. No need for app installations, logging in, or tedious script transfers. With the Super WiFi Duck, everything is at your fingertips, making it easier than ever to unleash the full potential of a BadUSB device.
Make memories, or just a cool camera-based project, with Adafruit’s MEMENTO Camera Board. It’s a development board with everything you need to create programmable camera and vision projects: with a camera module, TFT preview screen, buttons, SD card slot and driven by a powerful ESP32-S3 with 2 MB of PSRAM for buffering 5 MegaPixel camera images.
This product is just the mainboard, and does not come with an enclosure, LED ring, hardware, SD card, or battery.
The ESP32-S3 is a WiFi and Bluetooth LE capable, 240 MHz dual core Tensilica processor - much like the famous ESP32. The S3 adds native USB support so it’s great for use with Arduino or CircuitPython. The S3 also has the ability to interface with raw camera modules. The cameras require 12 GPIO pins and fast data transfer in order to get images off the sensor, and then a lot of memory for storing 2560 x 1920 images - which is why we picked an S3 module with 2MB of PSRAM so that we can read JPEGs into memory for saving onto an SD card.
To make the board easy to use we added a ton of supporting hardware, here’s a full list of the hardware included:
We’ve got both Arduino and CircuitPython example code that lets you preview the camera, adjust settings, and take photos that are saved to disk. However, we recommend CircuitPython because the compilation time in Arduino is pretty intense due to the huge amount of code required to run the camera. CircuitPython is fast to develop for and our library will make it easy to start making custom camera projects.
The Adafruit Feather ESP32 V2 is a new version of the original Adafruit HUZZAH32 ESP32 Feather. Both have the fabulous ESP32 WROOM module on there, which makes quick work of WiFi and Bluetooth projects that take advantage of Espressifs most popular chipset. We completely refreshed the board while moving from the obsolete CP2104 USB-serial chip to the available CH9102F.
Both boards say “HUZZAH32” on the bottom side, but they are different. Make sure you’ve chosen the correct download for the your board.
The Feather ESP32 V2 is a significant redesign, enough so we consider it a completely new product. It still features the ESP32 chip but has many upgrades and improvements:
However, in order to add the PSRAM, and use the new Pico module which was small enough to allow all the fun extras, some of the breakout pads have changed, so here’s what you need to know:
That module nestled in at the end of this Feather contains a dual-core ESP32 chip, 8 MB of SPI Flash, 2 MB of PSRAM, tuned PCB antenna, and all the passives you need to take advantage of this powerful new processor. The ESP32 has both WiFi and Bluetooth Classic/LE support. That means it’s perfect for just about any wireless or Internet-connected project.
Because it’s part of our Feather eco-system, you can take advantage of the 50+ Wings that we’ve designed to add all sorts of cool accessories. Plus that built in battery charging and monitoring you know and love with the ESP32 Feather is still there in this upgrade.
Features:
Comes fully assembled and tested, with a USB interface that lets you quickly use it with the Arduino IDE or the low-level ESP32 IDF. We also toss in some header so you can solder it in and plug into a solderless breadboard. Lipoly battery and USB cable not included (but we do have lots of options in the shop if you’d like!)
The ESP32-C6 is Espressif’s first Wi-Fi 6 SoC integrating 2.4 GHz Wi-Fi 6, Bluetooth 5 (LE) and the 802.15.4 protocol. It brings the goodness you know from the low-cost C3 series and improves it with Zigbee/802.15.4 at 2.4Ghz. That means it could make for great Matter development hardware!
We took our Feather ESP32-S2 and swapped out the ‘S2 for a C6. Plus some re-routing and here’s what we’ve got: a C6 Feather with lots of GPIO, lipoly charging and monitoring with the MAX17048, NeoPixel, I2C Stemma QT port, and a second low-quiescent LDO for disabling the I2C and NeoPixel when we want ultra-low power usage - as low as 17uA in deep sleep.
One thing to watch for is that, like the C3, the C6 does not have native USB. It does have a ‘built in’ USB Serial core that can be used for debugging, but it cannot act like a mouse, keyboard, or disk drive. That means if you are running CircuitPython you will need to use WiFi, Bluetooth or WebSerial for transferring files back and forth rather than drag-and-dropping to a drive. Ditto for the bootloader side, this chip cannot run UF2.
What’s Feather-shaped and has an ESP32-S2 WiFi module? What has a STEMMA QT connector for I2C devices? What has your favorite Espressif WiFi microcontroller and lots of Flash and RAM memory for your next IoT project? What will make your next IoT project flyyyyy?

Please note the Feather ESP32-S2 has a single-core 240 MHz chip, so it won’t be as fast as ESP32’s with dual-core. Also, there is no Bluetooth support. However, we are super excited about the ESP32-S2’s native USB which unlocks a lot of capabilities for advanced interfacing! This ESP32-S2 mini-module we are using on the Feather comes with 4 MB flash and 2 MB PSRAM so you can buffer massive JSON files for parsing!

0x77 for immediate ambient weather sensingLike Missy Elliot, we like to [“put our Feather] down, flip it and reverse it” and that’s exactly what we’ve done with this new development board. It’s basically our ESP32-S2 TFT Feather but with the 240x135 color TFT display on the back-side not the front-side. That makes it great for panel-mounted projects, particularly since we’ve also got some space for 3 buttons to go along. It’s like an all-in-one display interface dev board, powered by the fantastic ESP32-S2 WIFI module.

The color TFT is connected to the SPI pins, and uses additional pins for control that are not exposed to the breakout pads. It’s the same display as you see here, with 240x135 pixels and is IPS so you get bright color at any angle. The backlight is also connected to a separate pin so you can PWM the backlight up and down as desired.
For low power usage, the Feather has a second RT9080 regulator. The regulator is controlled with a GPIO pin on the enable line and can shut off power to the Stemma QT port and TFT. There is also a separate power pin for the NeoPixel that can be used to disable it for even lower quiescent power. With everything off and in deep sleep mode, the TFT feather uses about 40uA of current.

The Adafruit Feather HUZZAH32 is our original ESP32-based Feather, made with the official WROOM32 module. We packed everything you love about Feathers: built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and just about all of the GPIOs brought out so you can use it with any of our Feather Wings. We have other boards in the Feather family, check’em out here.
That module nestled in at the end of this Feather contains a dual-core ESP32 chip, 4 MB of SPI Flash, tuned antenna, and all the passives you need to take advantage of this powerful new processor. The ESP32 has both WiFi and Bluetooth Classic/LE support. That means it’s perfect for just about any wireless or Internet-connected project.
Don’t confuse this board with the similar, newer, Adafruit Feather ESP32 V2. Both boards say “HUZZAH32” on the bottom side, but they are different. Make sure you’ve chosen the correct download for your board.
Because it’s part of our Feather eco-system, you can take advantage of the 50+ Wings that we’ve designed to add all sorts of cool accessories.
The ESP32 is a perfect upgrade from the ESP8266 that has been so popular. In comparison, the ESP32 has way more GPIO, plenty of analog inputs, two analog outputs, multiple extra peripherals (like a spare UART), two cores so you don’t have to yield to the WiFi manager, much higher-speed processor, etc. etc! We think that as the ESP32 gets traction, we’ll see more people move to this chip exclusively, as it is so full-featured.
Here are specifications from Espressif about the ESP32:
Comes fully assembled and tested, with a USB interface that lets you quickly use it with the Arduino IDE or the low-level ESP32 IDF. We also toss in some header so you can solder it in and plug into a solderless breadboard. Lipoly battery and USB cable not included (but we do have lots of options in the shop if you’d like!)

A new chip means a new Feather, and the Raspberry Pi RP2040 is no exception. When we saw this chip we thought “this chip is going to be awesome when we give it the Feather Treatment” and so we did! This Feather features the RP2040, and all niceties you know and love about Feather.
Inside the RP2040 is a ‘permanent ROM’ USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar - we use the technique on all our native-USB boards. Just note you don’t double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!
The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD1). Since it is an M0 chip, it does not have a floating point unit, or DSP hardware support - so if you’re doing something with heavy floating-point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you’ll get close-to-M4 speeds!
For peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).
You’ll note there’s no I2S peripheral, or SDIO, or camera, what’s up with that? Well instead of having specific hardware support for serial-data-like peripherals like these, the RP2040 comes with the PIO state machine system which is a unique and powerful way to create custom hardware logic and data processing blocks that run on their own without taking up a CPU. For example, NeoPixels - often we bitbang the timing-specific protocol for these LEDs. For the RP2040, we instead use PIO object that reads in the data buffer and clocks out the right bitstream with perfect accuracy. Same with I2S audio in or out, LED matrix displays, 8-bit or SPI based TFTs, even VGA! In MicroPython and CircuitPython you can create PIO control commands to script the peripheral and load it in at runtime. There are 2 PIO peripherals with 4 state machines each.
There is great C/C++ support, unofficial (but really good) Arduino support, an official MicroPython port, and a CircuitPython port. We of course recommend CircuitPython because we think it’s the easiest way to get started and it has support with most of our drivers, displays, sensors, and more, supported out of the box so you can follow along with our CircuitPython projects and tutorials.
While the RP2040 has lots of onboard RAM (264KB), it does not have built-in FLASH memory. Instead, that is provided by the external QSPI flash chip. On this board there is 8 MB, which is shared between the program it’s running and any file storage used by MicroPython or CircuitPython. When using C/C++ you get the whole flash memory, if using Python you will have about 7 MB remaining for code, files, images, fonts, etc.
RP2040 Chip features:
Comes fully assembled and tested, with the UF2 USB bootloader. We also toss in some header, so you can solder it in and plug it into a solderless breadboard.
This is the Adafruit Feather RP2040 Adalogger - our take on an ‘all-in-one’ RP2040 data-logger (or data-reader) with built-in USB, battery charging, and a microSD holder ready to rock! We have other boards in the Feather family, check’em out here.
The RP2040 Adalogger is the same size and shape as a Feather and is intended to make your next data logging or data reading project super easy. Micro SD card socket wired for SPI or SDIO? Yes! STEMMA QT / Qwiic connector for fast I2C? Of course! Neopixel? It’s a-glowin’ This board will work excellently with Arduino or CircuitPython/MicroPython for any data recording/retreiving projects.
At the Feather’s heart is an RP2040 chip, clocked at 133 MHz and at 3.3V logic, the same one used in the Raspberry Pi Pico. This chip has a whopping 8MB of onboard QSPI FLASH and 264K of RAM! This makes it great for buffering and processing data before writing it to the SD card.
To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built-in battery charging. You don’t need a battery, it will run just fine straight from the USB Type C connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when it’s available.
Here’re some handy specs! You get:
Comes assembled and tested, with some header. You’ll need a soldering iron to attach the header for installing onto your Feather. Stacking headers will let you put another FeatherWing on top. Lipoly battery, MicroSD card, and USB cable not included (but we do have lots of options in the shop if you’d like!)
If you’d like quickly get started with CAN bus interfacing, with no soldering required, our Adafruit RP2040 CAN Bus Feather comes ready-to-rock with a microcontroller, CAN chipset and terminal blocks for instant gratification. The controller used is the MCP26525 (aka a MCP2515 with built-in transciever), an extremely popular and well-supported chipset that has drivers in Arduino and CircuitPython and only requires an SPI port and two pins for chip-select and IRQ. Use it to send and receive messages in either standard or extended format at up to 1 Mbps.
Feather is the development board specification from Adafruit, and like its namesake, it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores. We have other boards in the Feather family, check’em out here.
CAN Bus is a small-scale networking standard, originally designed for cars and, yes, busses, but is now used for many robotics or sensor networks that need better range and addressing than I2C and don’t have the pins or computational ability to talk on Ethernet. CAN is 2 wire differential, which means it’s good for long distances and noisy environments.
Messages are sent at about 1Mbps rate - you set the frequency for the bus and then all ‘joiners’ must match it, and have an address before the packet so that each node can listen in to messages just for it. New nodes can be attached easily because they just need to connect to the two data lines anywhere in the shared net. Each CAN device sends messages whenever it wants, and thanks to some clever data encoding, can detect if there’s a message collision and retransmit later.
We’ve added a few nice extras to this Feather to make it useful in many common CAN scenarios:
At the Feather’s heart is an RP2040 chip, clocked at 133 MHz and at 3.3V logic, the same one used in the Raspberry Pi Pico. This chip has a whopping 8 MB of onboard QSPI FLASH and 264K of RAM! There’s even room left over for a STEMMA QT connector for plug-and-play of I2C devices.

Wouldn’t it be cool if you could display images and graphics from a microcontroller directly to an HDMI monitor or television? We think so! So we designed this RP2040 Feather that has a digital video output (a.k.a DVI) that will work with any HDMI monitor or display. Note it doesn’t do audio, just graphics!
It’s kinda like we took our RP2040 Feather and DVI Breakout board and glued them together. You get all the pins for use on the Feather, the Lipoly battery support, USB C power / data, onboard NeoPixel, 8MB of FLASH for storing code and files, and then with the 8 unused pins, a DVI output that can be used with the PicoDVI library in Arduino or Pico SDK (note we don’t have Circuitpython support for DVI output at this time)
In Arduino, which is what we recommend, we use our fork of PicoDVI to create an internal framebuffer of 320x240 or 400x240 16-bit pixels that is then continuously blitted out as pixel-doubled 640x480 or 800x480 digital video. Whatever you ‘draw’ to the internal memory framebuffer appears instantly on the digital display in crisp color. Since the library is a subclass of AdafruitGFX, it’ll be familiar to folks who have used our TFT or OLED displays before.
Note that the DVI video generation uses one full core, both PIOs, and 150K (320x240) or 190K (400x240) of SRAM. It’s kinda maxed out so be aware of the remaining resource limitations.
We also connected the HDMI-connectors I2C pins to the SDA/SCL of the Feather (through a safe level shifter) so you can read the EDID EEPROM of displays, and have broken out the CEC and Utility pads. The Hot Plug Detect pin is also available on the very end of the 16-pin header. Read this pin to know when a display has been connected!
The Adafruit Feather series gives you lots of options for a small, portable, rechargeable microcontroller board. By picking a feather and stacking on a FeatherWing you can create advanced projects quickly. One popular combo is our Feather M4 or Feather RP2040 with a Prop-Maker FeatherWing on top to create animatronics or props that boot up instantly and can drive LEDs, and small speakers.
We’ve used the Prop-Maker FeatherWing to make lots of lil robots, swords, and other prop projects. However, what if we made it even easier for people to make props? What if we made it so many projects can be built with minimal or no soldering at all? Yeah that would be pretty nice!
Thus, the creation of the Adafruit RP2040 Prop-Maker Feather: an all-in-one combination of the Feather RP2040 with a Prop-Maker FeatherWing with a few tweaks based on feedback from expert prop-builders. Perfect for fitting into your next prop build! This Feather will unlock the ‘Imagineer’ inside all of us, with tons of stuff packed in to make sabers & swords, props, toys, mini robots, cosplay pieces, and more.
We looked at hundreds of prop builds, and thought about what would make for a great low-cost (but well-designed) add-on for our Feather boards. Here’s what we came up with:
At the Feather’s heart is an RP2040 chip, clocked at 133 MHz and at 3.3V logic, the same one used in the Raspberry Pi Pico. This chip has a whopping 8 MB of onboard QSPI FLASH and 264K of RAM! There’s even room left over for a STEMMA QT connector for plug-and-play of I2C devices.

If there is one thing Adafruit is known for, its mega-blinky-fun-rainbow-LEDs. We just love sticking NeoPixels anywhere and everywhere. When we saw the new ‘PIO’ peripheral on the RP2040 from Raspberry Pi, we just knew it would be perfect for driving large quantities of NeoPixels. So we created this board, the Adafruit Feather RP2040 SCORPIO, designed specifically for NeoPixel (WS2812) driving but also good for various other PIO-based projects that want to take advantage of the Feather pinout with 8 separate consecutive outputs (or inputs).
The RP2040 PIO state machine is perfect for LED driving: it can generate perfect waveforms, with up to 8 outputs concurrently, all through DMA. That means that you don’t need to use any processor time to bit-bang-out the LED data. Just set up the buffer and tell the PIO peripheral to ‘make it so’ and it will shove that data to the 8 outputs without delay while your code can continue to read buttons, play music, run CircuitPython - whatever you like!
The SCORPIO has a clever pinout, where all the standard Feather pins are the same as the GPIO pins, plus the standard I2C, SPI and UART lines - and theres still enough pins left over to have 8 consecutive pins for PIO usage on GPIO16 through GPIO23 inclusive.
To make NeoPixel usage glitch-free there is a 3V->5V level shifter so that the output logic is 5V. If you happen to want 3V signals, you can adjust the shifter voltage with a jumper on the bottom. It’s also possible to flip the direction of the level shifter to make the 8 I/O pins inputs - say for making a logic analyzer - with a directional jumper selection also on the bottom of the PCB.
The RP2040 SCORPIO also has a ton of RAM, 264KB, making it trivial to buffer huge numbers of NeoPixels…several thousand if needed. In fact there’s so much RAM you can even dither the pixels to for finer brightness control, for better-looking LEDs at low brightness or for gamma correction.
We have NeoPXL8 driver code available in Arduino and CircuitPython, so you can jump immediately to making beautiful artworks driven by the Adafruit SCORPIO.
Easy e-paper and RP2040 finally come to your Feather with this Adafruit RP2040 Feather Think Ink that’s designed to make it a breeze to add almost any common e-Ink/e-Paper display. Chances are you’ve seen one of those new-fangled ‘e-readers’ like the Kindle or Nook. They have gigantic electronic paper ‘static’ displays - that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!
We’ve liked these displays for a long time, and we’ve got Arduino/CircuitPython drivers for tons of the various display chipsets, so wouldn’t an e-paper RP2040 Feather make a ton of sense? Luckily for us, just about every small-medium size EInk display made these days has a standard 24-pin connection. This Feather will add all the power supply support circuitry and level shifting so you can attach your favorite display - we’ve tested it with up to 5.6” sized 7-color ACeP displays.
Since all ePaper displays with the 24-pin interface require you to buffer the layers of data and write them all out at once over SPI, the RP2040 chip is an excellent driver. It has 264K of internal SRAM so even with the largest displays, there’s plenty of memory to store all the image data plus run your own code. We also put the display on it’s own SPI port so that the Feather’s main SPI port can be used for other peripheral devices.

You’re probably really used to microcontroller boards with USB, but what about a dev board with two? Two is more than one, so that makes it twice as good! And the Adafruit Feather RP2040 with USB Host is definitely double-the-fun of our other Feather RP2040 boards, with a USB Type A port on the end for connecting USB devices to.
Now you might be thinking “hey waitaminute, the RP2040 doesn’t have two USB port peripherals???” and you’d be correct! But what it does have is a nifty PIO peripheral that can be (ab)used to emulate a USB host peripheral. You get to keep the main USB port for uploading, debugging, and data communication, while at the same time sending and receiving data to just-about-any USB device. This work is originally by sekigon on GitHub, and if you’re using Pico SDK that’s still the recommended library to use.
Currently, support for the USB Host peripheral is only in Arduino. So check out the TinyUSB ‘dual role’ examples for some things you can do! For example, datalogging to a USB Key. Or reading from another device/microcontroller that has USB CDC serial interface. Or creating an HID re-mapper. Or connecting to weird devices that require firmware-updates like the Cypress EZ-USB based Intellikeys communications board.
The Adafruit Feather RP2040 features the Raspberry Pi RP2040 chip with dual ARM Cortex-M0+ cores running at 133 MHz, 264KB of RAM, 8MB of QSPI flash, a STEMMA QT connector, USB-C, and built-in LiPoly battery charging. This build uses the Zephyr RTOS port of CircuitPython, which is currently in alpha.
Note: This is the Zephyr RTOS port of CircuitPython for this board. For the standard CircuitPython build, see the Feather RP2040 page.
RP2350 flies high with the Feather format - now you can use any FeatherWings with this battery-powered dev board. It comes with 8MB of flash, 22pin HSTX output port, Stemma QT, debug SWD, and optional PSRAM spot. It’s our first RP2350 board and we crammed a ton of goodies into our classic Feather format. It’s an excellent starter board to go along with your Pico 2.
The RP2350 is Raspberry Pi’s second microcontroller chip following their breakout-hit the RP2040. Building on their success, the RP2350 upgrades the dual M0 core to dual M33 cores with 150 MHz clock rate. The M33 is a much newer Arm chipset, we’ve found that firmware runs about twice as fast. Especially given that we now have hardware floating point support. Also, the RP2350 has twice as much SRAM: 520KB instead of 264KB which means that micropython/circuitpython runs great and also IoT projects that need a lot of memory buffer space will run better. Other improvements include, 3 PIO blocks instead of 2, TrustZone secure boot, and a special High Speed Transmit (HSTX) peripheral that drives 4 lanes of differential data transmission such as DVI output without needing to overclock or use PIO.
For peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 24 PWM channels, each pin has a channel it can be set to (ditto on the pinout).
Feather RP2350 HSTX Specifications:
Inside the RP2350 is a ‘permanent ROM’ USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar - we use the technique on all our native-USB boards.

RP2350 Chip features:
Please note: The Adafruit Feather RP2350 HSTX comes with the A2 version of the RP2350, which is affected by the E9 erratum. This errata affects some uses of GPIO and PIO such as high-impedance inputs and the internal pulldowns. You may need to use 8.2K or smaller resistors if pull-downs are required. At this time, Sept 9 2024, there is no other version of the RP2350 available - only the A2 version.

We were catching up on a recent hackaday hackchat with eben upton and learned some fun facts: such as the DVI hack for the RP2040 was inspired by a device called the IchigoJam. we remember reading about this back when it was an LPC1114, now it uses an RP2040. well, we’re wrapping up the Metro RP2350 and lately we’ve been joking around that with DVI output and USB Host support via bit-banged PIO, you could sorta build a little stand-alone computer.
Well, one pear-green-tea-fueled-afternoon later we tried our hand at designing a ‘credit card sized’ computer - that’s 3.375” x 2.125”, about the same size as a business card and turns out there’s even a standard named for it: ISO/IEC 7810 ID-1.
Anyhow, with the extra pins of the QFN-80 RP2350B, we’re able to jam a ridonkulous amount of hardware into this shape:
Home is where the heart is…it’s also where all we keep all our electronic bits. So why not wire it up with sensors and actuators to turn our house into an electronic wonderland. Whether it’s tracking the environmental temperature and humidity in your laundry room, or notifying you when someone is detected in the kitchen, to sensing when a window was left open, or logging when your cat leaves through the pet door, this board is designed to make it way easy to make WiFi-connected home automation projects.
The main processor is the ESP32-S2, which has the advantage of the low cost and power of the ESP32 with the flexibility of CircuitPython support thanks to native USB support. There’s also Arduino support for this chip, and many existing ESP32 projects seem to run as-is. Note this chip does not have BLE support, but for WiFi projects its great. You can use it to connect to IoT services or just the Internet in general, with SSL support and this module has plenty of PSRAM for any kind of data processing.
The board is designed to make it easy to wire up sensors with little or no soldering. There are built in sensors for light, pressure, humidity and temperature sensors. Three JST PH plugs allow for quick connection of STEMMA boards that use digital or analog I/O, and there’s a STEMMA QT port for any I2C devices.
Squeeeeze down your next ESP32 project to its bare-bones essential with the Adafruit HUZZAH32 Breakout. This breakout is basically the ‘big sister’ of our HUZZAH 8266, but instead of an ESP8266 it has the ‘32! We’ve pared down our popular Feather ESP32, removing the battery charger and USB-serial converter. You just get a regulator, some protection diodes, two buttons and an LED. For some projects, where price and size are at a premium, you can program this board over the ‘FTDI cable’ breakout when needed, and leave it alone otherwise.
Note that this board doesn’t come with a USB to serial converter chip and auto-reset circuit. Instead, you will need to plug in a CP2104 Friend or FTDI cable. Then, before uploading code, put it into bootloader mode by holding down the GPIO #0 button and clicking Reset button, then releasing the #0 button.
That module in the middle of the breakout contains a dual-core ESP32 chip, 4 MB of SPI Flash, tuned antenna, and all the passives you need to take advantage of this powerful new processor. The ESP32 has both WiFi and Bluetooth Classic/LE support. That means it’s perfect for just about any wireless or Internet-connected project.
The ESP32 is a perfect upgrade from the ESP8266 that has been so popular. In comparison, the ESP32 has way more GPIO, plenty of analog inputs, two analog outputs, multiple extra peripherals (like a spare UART), two cores so you don’t have to yield to the WiFi manager, much higher-speed processor, etc. etc!
Comes fully assembled and tested, pre-programmed with ESP32 SPI WiFi co-processor firmware that you can use in CircuitPython to use this into a WiFi co-processsor over SPI + 2 pins. We also toss in some header so you can solder it in and plug into a solderless breadboard.
Here are specifications from Espressif about the ESP32:

What’s smaller than a Feather but larger than a Trinket? It’s an Adafruit ItsyBitsy ESP32, a powerful processor PCB with a plethora of pins! It features the ESP32 Pico module, an FCC-certified module that contains an ESP32 chip with dual-core 240MHz Tensilica processor, WiFi, and Bluetooth classic + BLE, configured with 8 MB of Flash memory, and 2 MB of PSRAM.
We’ve added some handy accessories like a USB to serial converter chip, power regulator, USB Micro B, buttons, NeoPixel, and Stemma QT I2C connector to outfit this super-hero chip for any task you want to throw it at. This is also an ultra low power ESP32 board with a deep sleep current consumption of 10uA!
At the core of the Itsy is the ESP32 (PICO ECO V3) chip, which is a single 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC’s 40 nm low-power technology. The ESP32 PICO in particular integrates all peripheral components seamlessly, including a crystal oscillator, flash, PSRAM, filter capacitors, and RF matching links in one single package. This makes it perfect for stuffing into a small space as the ItsyBitsy.
Please note, like other ESP32 modules, the ItsyBitsy ESP32 does not have native USB support - instead, there’s a USB to serial converter chip. This means it cannot act like a USB keyboard or mouse, but it does have BLE and BT classic, so you could use it wirelessly.
A new chip means a new ItsyBitsy, and the Raspberry Pi RP2040 is no exception. When we saw this chip we thought “this chip is going to be awesome when we give it the ItsyBitsy teensy-weensy Treatment” and so we did! This Itsy’ features the RP2040, and all niceties you know and love about the ItsyBitsy family.
What’s smaller than a Feather but larger than a Trinket? It’s an Adafruit ItsyBitsy RP2040 featuring the Raspberry Pi RP2040! Small, powerful, with a ultra fast duel Cortex M0+ processor running at 125 MHz - this microcontroller board is perfect when you want something very compact, with lots of horsepower and a bunch of pins. This Itsy has sports car speed, but SUV roominess with 4 MB of FLASH and 264 KB of SRAM.
ItsyBitsy RP2040 is only 1.4” long by 0.7” wide, but has 6 power pins, 23 digital GPIO pins (4 of which can be analog in and 16x PWM out). It’s the same chip as the Feather RP2040 and Raspberry Pi Pico but really really small. So it’s great once you’ve finished up a prototype, and want to make the project much smaller. It even comes with 4MB of SPI Flash built in, for data logging, file storage, or CircuitPython/MicroPython code.
Inside the RP2040 is a ‘permanent ROM’ USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar - we use the technique on all our native-USB boards. Just note you don’t double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!
The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit or DSP hardware support - so if you’re doing something with heavy floating point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you’ll get close-to-M4 speeds!
For peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).
You’ll note there’s no I2S peripheral, or SDIO, or camera, what’s up with that? Well instead of having specific hardware support for serial-data-like peripherals like these, the RP2040 comes with the PIO state machine system which is a unique and powerful way to create custom hardware logic and data processing blocks that run on their own without taking up a CPU. For example, NeoPixels - often we bitbang the timing-specific protocol for these LEDs. For the RP2040, we instead use PIO object that reads in the data buffer and clocks out the right bitstream with perfect accuracy. Same with I2S audio in or out, LED matrix displays, 8-bit or SPI based TFTs, even VGA! In MicroPython and CircuitPython you can create PIO control commands to script the peripheral and load it in at runtime. There are 2 PIO peripherals with 4 state machines each.
At the time of launch, there is no Arduino core support for this board. There is great C/C++ support, an official MicroPython port, and a CircuitPython port! We of course recommend CircuitPython because we think it’s the easiest way to get started and it has support with most of our drivers, displays, sensors, and more, supported out of the box so you can follow along with our CircuitPython projects and tutorials.
This Itsy comes with loose 0.1” headers you can solder in for breadboard use!
While the RP2040 has lots of onboard RAM (264 KB), it does not have built-in FLASH memory. Instead, that is provided by the external QSPI flash chip. On this board there is 2 MB, which is shared between the program it’s running and any file storage used by MicroPython or CircuitPython. When using C/C++ you get the whole flash memory, if using Python you will have about 1 MB remaining for code, files, images, fonts, etc.
RP2040 Chip features:
A wild Kee Boar appears! It’s a shiny KB2040! An Arduino Pro Micro-shaped board for Keebs with RP2040. (#keeblife 4 evah) A lot of folks like using Adafruit parts for their Keeb builds – but with the ItsyBitsy not being pin-compatible with the Pro Micro pinout, it really wasn’t very easy without some sort of adapter plate.
Now we’re seeing lots of people use CircuitPython for keebs, which is awesome! So why not try our hands at spinning up a pro-micro-compatible RP2040 board? The RP2040 is plenty powerful, low-cost, and makes for an excellent keeb driver chip.
We mixed together what we liked most about the SparkFun Pro Micro RP2040 (Qwiic / STEMMA QT I2C port on the end, so good!) and Elite-C (castellated pads & pins for D+ and D-) and our existing RP2040 boards (boot button can be used for user, 8MB QSPI flash, onboard NeoPixel, jumper for skipping the diode/fuse for high power RGB LEDs or USB hosting). We even got it to all fit on a 2-layer PCB with 7/7 routing – just needed to make the smallest caps and resistors 0402.
With 20 GPIO available (18 on castellated pins, 2 on STEMMA QT port) you can easily make up to 100-keys matrices, or common 65% 5x15 layouts. Use a plug-and-play QT cable to connect to the last two pins without having to do any desoldering/rework.
This board is designed to be a thin, bluetooth-enabled driver board for our Adafruit LED Glasses RGB LED matrix. That said, it’s a perfectly good stand-alone development board for the Nordic nRF52840 chipset, with a very slim design, optional LiPo battery support, a few sensors, and a Stemma QT port for adding other devices or sensors with I2C plug-and-play.
The driver looks a little like a Feather but it does not have any breakout pins to keep it very compact. If you need access to GPIO pins, we recommend an nRF52840 ItsyBitsy, nRF52840 Feather or Feather Sense.
In exchange for GPIO outputs, we added some sensors on instead: each board comes with a LIS3DH triple-axis accelerometer that can be used for motion and orientation sensing, and a PDM digital microphone for audio sensing. To add more sensors or connect to the LED Glasses front panel, there’s a STEMMA QT connector for plug-and-play I2C support.
Unlike our Itsy/Feather boards, this driver also comes with a proper on/off switch which will cut power to the microcontroller and external sensors. There’s optional LiPo charge support because we think that many folks will want to power this board with AAA or coin cell batteries. If you’d like to enable LiPo charging, short the jumper on the back and then make sure to only use 4.2 V/3.7 V rechargeable batteries in the battery port.
The nRF52840 is a lovely Bluetooth LE microcontroller, with good support in both Arduino and CircuitPython. It feathers a Cortex M4 processor with 1 MB of FLASH and 256 KB of SRAM. Best of all, it’s got that native USB! Finally, no need for a separate USB serial chip like CP2104 or FT232. Serial is handled as a USB CDC descriptor, and the chip can act like a keyboard, mouse, MIDI device or even disk drive. This chip has TinyUSB support - that means you can use it with Arduino as a native USB device and act as UART (CDC), HID, Mass Storage, MIDI and more!
For developers, we pre-programed the chip with our UF2 bootloader, which can use either command line UART programming with nrfutil (we use this for Arduino) or drag-n-drop mass storage, for CircuitPython installation and also because mass-storage-drive bootloaders make updating firmware so easy. Want to program the chip directly? You can use our command line tools with your favorite editor and toolchain. If you want to use an SWD programmer/debugger (for even more advanced usage), we have broken out the SWD pads for easy soldering.
Strap yourself in, we’re launching in T-minus 10 seconds…Destination? A new Class M planet called MACROPAD! M here, stands for Microcontroller because this 3x4 keyboard controller features technology from the Raspberry Pi sector: say hello to the RP2040. It’s speedy little microcontroller with lots of GPIO pins and a 64 times more RAM than the Apollo Guidance Computer. We added 8 MB of flash memory for plenty of storage.
Get ready to upgrade your desk’s mission control station with a CircuitPython or Arduino powered Macropad - complete with 12 buttons, OLED display, speaker and rotary encoder. Customize it for your spacecraft to help guide you through the great reaches of the unknown. (Or just have it type out your favorite emojis.)
Each of the 12 sockets can accept a Cherry MX-compatible key switch. No soldering required, just snap it in! Use any key switch you like - but we recommend ones with slots that will allow the matching twelve NeoPixels underneath to shine through.
This space-ship is also fitted with a 128x64 monochome OLED for a crisp heads-up display that can be used in Arduino or CircuitPython to display keymaps, stats, computer performance, etc. There’s also a rotary encoder with push-button soldered in. Twist and turn it or push to change volume or monitor brightness or scroll: whatever you like! A tiny speaker can give audio feedback or play fun bleepy tunes.
Want to add more hardware? No worries - a STEMMA QT port on the side lets you connect any I2C add-on peripherals from the massive STEMMA QT / Qwiic family of plug in boards.
This macropad was originally designed to be programmed in Arduino or CircuitPython, but you can also use QMK or KMK firmware if you prefer!
UPDATE: The Adafruit MagTag has a new 2025 Edition! As of July 22, 2025, the display has been updated (the old one was discontinued). You must use CircuitPython 10.0.0-beta.1 or later to support the new display. It will also work on older MagTags.
The Adafruit MagTag combines the new ESP32-S2 wireless module and a 2.9” grayscale E-Ink display to make a low-power IoT display that can show data on its screen even when power is removed! The ESP32-S2 is great because it builds on the years of code and support for the ESP32 and also adds native USB support so you can use this board with Arduino or CircuitPython!
We designed this board to be low-power friendly - with a spot for a 350 or 420 mAh battery and built in battery charging over USB C. During deep sleep, with the NeoPixels and speaker amplifier disabled, we measured 250uA power draw so you can run for a few weeks between charges.
And of course, the Mag in MagTag stands for magnetic. We have four M3 standoffs that will work perfectly with these mini magnet feet. (Originally they’re designed for RGB Matrices but they’ll do an excellent job here as well). Screw on the feet and you can attach this display to a metallic shelf, fridge, or bench.
Folks love our wide selection of RGB matrices and accessories for making custom colorful LED displays… and our RGB Matrix Shields and FeatherWings can be quickly soldered together to make the wiring much easier. But what if we made it even easier than that? Like, no solder, no wiring, just instant plug-and-play? Dream no more - with the Adafruit Matrix Portal S3 add-on for RGB Matrices, there’s never been an easier way to create powerful Internet-connected LED displays.
You can plug directly into the back of any HUB-75 compatible display (all the ones we stock will work) from 16x32 up to 64x64 or use the stock 2x8 IDC cables to plug into the front. Use the included screws to attach the power cable to the power plugs with a common screwdriver, then power it with any USB C power supply. Chain dozens of displays for long stretches, or you can panelize them in a grid for bigger displays. For larger projects, power the matrices with a separate 5V power adapter.
Then code up your project in CircuitPython or Arduino, our Protomatter matrix library works great on the ESP32-S3 chipset, knowing that you’ve got the wiring and level shifting all handled. Here’s what you get:
The Matrix Portal uses an Espressif ESP32-S3 Wi-Fi+BLE chipset, and has dropped the SAMD51 from the original Matrix Portal due to silicon shortages. But turns out the S3 is really great at doing all the work of the original all on its own:
Comes with one fully programmed and assembled MatrixPortal, preprogrammed with a basic display demo for 32x64 LED matrices.
What’s Metro shaped and has an ESP32-S2 WiFi module? What has a STEMMA QT connector for I2C devices, and a Lipoly charger circuit? What’s finishing up testing and nearly ready for fabrication? That’s right - its the new Adafruit Metro ESP32-S2! With native USB and a load of PSRAM this board is perfect for use with CircuitPython or Arduino, to add low-cost WiFi while keeping shield-compatibility.
What’s Metro-shaped and has an ESP32-S3 WiFi module? What has a STEMMA QT connector for I2C devices and a Lipoly charger circuit? What has your favorite Espressif WiFi microcontroller and lots of memory for your next IoT project?
That’s right - it’s the new Adafruit Metro ESP32-*S3*! With native USB and a load of PSRAM, this board is perfect for use with CircuitPython or Arduino to add low-cost WiFi while retaining shield compatibility.
The ESP32-S3 is a highly-integrated, low-power, 2.4 GHz Wi-Fi/BLE System-on-Chip (SoC) solution that has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements and AI acceleration. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.
The Metro ESP32-S3 has a dual-core 240 MHz chip, so it is comparable to ESP32’s dual-core. However, there is no Bluetooth Classic support, only Bluetooth LE. This chip is a great step up from the earlier ESP32-S2! This ESP32-S3 mini-module we are using on the Metro comes with massive 16 MB flash and 8 MB PSRAM, as well as lots of 512KB of SRAM so it’s perfect for use with CircuitPython support or any time massive buffers are needed: for fast memory access use SRAM, for slower-but-roomier access use PSRAM. It’s also great for use in ESP-IDF or with Arduino support.
Features:
Your favorite electronics companies have collaborated to make the fastest Metro ever! For this new product, DigiKey, NXP and Adafruit all contributed the stuff they know best: shipping parts fast (DigiKey), designing microcontrollers (NXP) and crafting great products with tutorials (that’s us, Adafruit!)
We teamed up to present to you the Adafruit Metro M7 with microSD! An NXP iMX RT1011 microcontroller powers this board with a 500 MHz ARM Cortex M7 processor. There’s 8 MB of execute-in-place QSPI for firmware + disk storage and 128KB of SRAM in-chip. Arduino-compatible headers make using any ‘shield’ daughterboard easy. And, as you can expect, there’s a micro SD card slot wired up right on board so that you can read files or data log easily to removable, wear-leveled storage.
The iMX series of chips is the fastest microcontrollers around, with a Cortex M7 processor that is more powerful than the M0 or M4, and clock speeds of 500MHz+. For pure performance, there’s nothing better! This chip family is well known for being featured in the Teensy 4 dev board series. Now we have a Metro-shaped board so you can use many Arduino shields, that is fully open source so you can adapt the design to create your own custom layouts, and a USB drag-n-drop bootloader plus CircuitPython support for easy development. Beginners and experts alike will enjoy the combination of low cost, roomy memory and storage, and no-soldering quick start.
Please note that this board does not have Arduino or Platform.io support. You can program it with CircuitPython, a fast-to-start embedded version of the popular Python programming language, or with MCU Xpresso IDE for C/C++ advanced embedded development.

Choo! Choo! This is the RP2040 Metro Line, making all station stops at “Dual Cortex M0+ mountain”, “264K RAM round-about” and “16 Megabytes of Flash town”. This train is piled high with hardware that complements the Raspberry Pi RP2040 chip to make it an excellent development board for projects that want Arduino-shape-compatibility or just need the extra space and debugging ports.
You may be wondering about the RX-TX switch: we added this because traditional Arduino board start counting the GPIO for the digital pins with 0-7 and then 8-13. However, the D0/D1 pins are also traditionally the hardware UART Serial1, where D0 is Rx and D1 is Tx. On the RP2040, however, the UART pins are the other around: D0 is Tx and D1 is Rx. Thus a DPDT switch: flip one way to have the GPIO go in order of 0-7, flip the other way to have the logical locations of the hardware UART correct but now the pin order is 1, 0, 2, 3..7. Of course, it’s also handy if, like us, you often swap the pins - now you don’t need to require or cut/solder traces!
The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21).

Choo! Choo!

The Adafruit Sparkle Motion Mini is part of our series of “Sparkle Motion” boards, that are our attempt to make the best small WLED-friendly smart LED driving board in the whole world. Our resident mermaid, firepixie makes a lot of projects with WLED and she loves it! So how can we make something that will be powerful enough to drive advanced LED projects that need a compact design?
The Mini version of the Sparkle Motion is a simpler version of our full-featured Sparkle Motion, we give up the high voltage support and built in IR receiver, in order to make it under 1 square inch in size! By using a 4-layer board and double-sided assembly we’ve put together this feature set:
While we recommend it for use with WLED, it will also work just fine as a compact ESP32 board for use with Arduino, ESP-IDF, MicroPython, CircuitPython or any other ESP32 supported codebase.
Note that unlike the classic Sparkle Motion board, we don’t include terminal blocks pre-soldered to keep the board very slim. We do stock the matching blocks if you want them, a small amount of soldering is required to attach them. Also, unlike the bigger version, we dropped the on-board IR receiver - however its easy to add one by plugging in a JST SH 3-pin socket cable and slotting in an IR receiver module.
It’s half USB Key, half Adafruit Trinket, half mechanical keeb…it’s NeoKey Trinkey, the circuit board with a Trinket M0 heart, a NeoPixel glow, and a Cherry MX-compatible. We were inspired by single-key macro pads we’ve seen. So we thought, hey what if we made something like that that plugs right into your computer’s USB port, with a fully programmable color NeoPixel? And this is what we came up with!
The PCB is designed to slip into any USB A port on a computer or laptop. There’s an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to a Cherry MX-compatible switch. Another connects to a NeoPixel LED. The third pin can be used as a capacitive touch input. A reset button lets you enter bootloader mode if necessary. That’s it!
The SAMD21 can run CircuitPython or Arduino very nicely - with existing NeoPixel and our FreeTouch libraries for the capacitive touch input. Over the USB connection you can have serial, MIDI or HID connectivity. The NeoKey Trinkey is perfect for simple projects that can use a few user inputs and colorful output. Maybe you’ll set it up as a macro-controller, or a password-enterer, or an Escape key for your MacBook.
Please note this board DOES NOT come with a key soldered in - we expect folks to pick their favorite MX-compatible key switch and key cap! Two solder points and you’re done.
We think it’s just an adorable little board, small and durable and inexpensive enough that it could be a first microcontroller board, or inspiration for advanced developers to make something simple and fun.
The Adafruit P4 GPIO is a development board based on the Espressif ESP32-P4 (rev 3+) dual-core RISC-V SoC running at up to 400 MHz, paired with 16 MB of QSPI flash and 32 MB of HPI PSRAM. The board breaks out the ESP32-P4 GPIO pins across four 8-pin headers (B1–B4), with a status NeoPixel on GPIO52 and a boot button on GPIO35. Two USB ports are provided: a high-speed USB device on the J1 connector and a full-speed USB on J2.
This board is not yet available for purchase. Board definition by Scott Shawcroft (@tannewt).
Coming soon from Adafruit, check out the weekly “Top Secret” segment on ASK AN ENGINEER or the upcoming new product videos on YouTube.
It’s half USB Key, half Adafruit Trinket M0, half APDS9960 breakout…it’s Proximity Trinkey, the circuit board with a Trinket M0 heart, APDS9960 Proximity, Light, RGB, and Gesture Sensor, and two RGB NeoPixels for a customizable glow. We wanted to make it super-easy to add one of our most popular combination-sensors to any computer with a USB port and this one is ready to go in an instant.
The PCB is designed to slip into any USB A port on a computer or laptop. There’s an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to the two NeoPixel LEDs. Two other pins are used as capacitive touch inputs on the end - if you look carefully you can see the slotted end has left and right touch pads. A reset button lets you enter bootloader mode if necessary. That’s it!
The SAMD21 can run CircuitPython or Arduino very nicely - both have existing APDS9960, NeoPixel and our FreeTouch (capacitive touch) libraries. Over the USB connection, you can have serial, MIDI, or HID connectivity. The Proximity Trinkey is perfect for simple projects that want to use motion, light or color sensing as an input to make fun and intuitive user experiences.
The star of this Trinkey is the APDS9960 from Avago Technologies, which has a few different capabilities thanks to integrated IR LED, photodiodes, and RGB sensing:
We think it’s just an adorable little board, small and durable and inexpensive enough that it could be a first microcontroller board or inspiration for advanced developers to make something simple and fun.
It’s half USB Key, half Adafruit QT Py, and a lotta RP2040…it’s Trinkey QT2040, the circuit board with an RP2040 heart and Stemma QT legs. Folks are loving the QT Py 2040 we made, but maybe you want something plug-and-play. So we thought, hey what if we made something like that plugs right into your computer’s USB port? And this is what we came up with!
The PCB is designed to slip into any USB A port on a computer or laptop. There’s an RP2040 microcontroller on board with just enough circuitry to keep it happy. There’s an RGB NeoPixel, a reset and bootloader or user button and a STEMMA QT Port on the end. That’s it!
With the body of the board being 1.0” x 0.7” and four mounting holes, you can attach just about any of our QT boards right on (some are a little larger so just check that has the holes in the same locations). Use M2.5 sized standoffs and screws to do so, you could use 2 diagonal at a minimum. Then use a shorty QT cable and you’ve got a custom sensor Trinkey for any sensor purpose.
The board comes with 8 MB of QSPI flash memory so you can put all of our CircuitPython drivers on the disk!
This dev board is like when you’re watching a super-hero movie and the protagonist shows up in a totally amazing costume in the third act and you’re like ‘OMG! That’s the hero and they’re here to kick some serious butt!” but in this case its a microcontroller.
This QT Py board is a thumbnail-sized PCB that features the ESP32 Pico V3 02, an all-in-one chip that has an ESP32 chip with dual-core 240MHz Tensilica processor, WiFi and Bluetooth classic + BLE, adds a bunch of required passives and oscillator, 8 MB of Flash memory and 2 MB of PSRAM. We add a USB to serial converter chip, some more passives, an antenna, USB C, buttons, NeoPixel and QT connector to outfit this super-hero chip for any task you want to throw it at.
At the core of ESP32-PICO-V3-02 is the ESP32 (ECO V3) chip, which is a single 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC’s 40 nm low-power technology. ESP32-PICO-V3-02 integrates all peripheral components seamlessly, including a crystal oscillator, flash, PSRAM, filter capacitors, and RF matching links in one single package. This makes it perfect for stuffing into such a small space as the QT Py.
Please note the QT Py ESP32 Pico does not have native USB support - instead there’s a USB to serial converter chip. This means it cannot act like a USB keyboard or mouse - but it does have BLE and BT classic so you could wireless.
OLEDs! Inertial Measurement Units! Sensors a-plenty. All plug-and-play thanks to the innovative chainable design: SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so you don’t even need to solder! Just plug in a compatible cable and attach it to your MCU of choice, and you’re ready to load up some software and measure some light. Seeed Grove I2C boards will also work with this adapter cable.
Pinout and shape are Seeed Xiao compatible, with castellated pads. In addition to the QT connector, we also added an RGB NeoPixel (with controllable power pin to allow for ultra-low-power usage), a reset button (great for restarting your program or entering the bootloader), and a button on GPIO 0 for entering the ROM bootloader or for user input
Runs Arduino like a dream, or use the ESP IDF for more control over your projects.
What’s life without a little RISC? This miniature dev board is perfect for small projects: it comes with our favorite connector - the STEMMA QT, a chainable I2C port, WiFi, Bluetooth LE, and plenty of FLASH and RAM memory for many IoT projects. What a cutie pie! Or is it… a QT Py? This diminutive dev board comes with a RISC-V IoT microcontroller, the ESP32-C3!
ESP32-C3 is a low-cost microcontroller from Espressif that supports 2.4 GHz Wi-Fi and Bluetooth® Low Energy (Bluetooth LE). It has built-in USB-to-Serial, but not native USB - it cannot act as a keyboard or disk drive. The chip used here has 4MB of Flash memory, 400 KB of SRAM and can easily handle TLS connections.
The ESP32-C3 integrates a rich set of peripherals, ranging from UART, I2C, I2S, remote control peripheral, LED PWM controller, general DMA controller, TWAI controller, USB Serial/JTAG controller, temperature sensor, and ADC. It also includes SPI, Dual SPI, and Quad SPI interfaces. There is no DAC or native capacitive touch.
There’s a minimum number of pins on this chip, it’s specifically designed to be low cost and for simpler projects than ESP32-Sx or ESP32 classics with their large number of GPIO. Think of it more as an intended replacement to the ESP8266 than to the ESP32!
With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.
Please note: The C3 uses RISC V as a core, not Tensilica, and has Bluetooth LE (not classic!). The BLE core supports BT version 5 including Mesh

What will make your next IoT project flyyyyy? What a cutie pie! Or is it… a QT Py? This diminutive dev board comes with one of our new favorite lil chips, the ESP32-S2!
The ESP32-S2 is a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) solution that now has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.
Please note the QT Py ESP32-S2 has a single-core 240 MHz chip, so it won’t be as fast as ESP32’s with dual-core. Also, there is no Bluetooth support. However, we are super excited about the ESP32-S2’s native USB which unlocks a lot of capabilities for advanced interfacing! This ESP32-S2 mini-module we are using on the QT Py comes with 4 MB flash and 2 MB PSRAM so you can buffer massive JSON files for parsing!
OLEDs! Inertial Measurement Units! Sensors a-plenty. All plug-and-play thanks to the innovative chainable design: SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so you don’t even need to solder! Just plug in a compatible cable and attach it to your MCU of choice, and you’re ready to load up some software and measure some light. Seeed Grove I2C boards will also work with this adapter cable.
Pinout and shape are Seeed Xiao compatible, with castellated pads so you can solder it flat to a PCB. In addition to the QT connector, we also added an RGB NeoPixel (with controllable power pin to allow for ultra-low-power usage), a reset button (great for restarting your program or entering the bootloader) and a button on GPIO 0 for entering the ROM bootloader or for user input.
Runs Arduino like a dream, and CircuitPython projects are fantastically fun.
The ESP32-S3 has arrived in QT Py format - and what a great way to get started with this powerful new chip from Espressif! With dual 240 MHz cores, WiFi and BLE support, and native USB, this QT Py is great for powering your IoT projects. Now we even have this powerhouse of a board with built in 2 Megabytes of PSRAM for when you need to buffer large datasets in memory.

What a cutie pie! Or is it… a QT Py? This diminutive dev board comes with one of our new favorite chip, the RP2040. It’s been made famous in the new Raspberry Pi Pico and our Feather RP2040 and ItsyBitsy RP2040, but what if we wanted something really smol?
A new chip means a new QT Py, and the Raspberry Pi RP2040 is no exception. When we saw this chip we thought “this chip is going to be awesome when we give it the cuuutie QT Py Treatment”, and so we did! This QT Py features the RP2040, and all niceties you know and love about the original QT Py.
The star of the QT Py is our favorite connector - the STEMMA QT, a chainable I2C port that can be used with any of our STEMMA QT sensors and accessories. Having this connector means you don’t need to do any soldering to get started.
What can you pop into the QT port? How about OLEDs! Inertial Measurment Units! Sensors a-plenty. All plug-and-play thanks to the innovative chainable design: SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so you don’t even need to solder. Just plug in a compatible cable and attach it to your MCU of choice, and you’re ready to load up some software and measure some light.
Use any SparkFun Qwiic boards! Seeed Grove I2C boards will also work with this adapter cable.
There is great C/C++ support, unofficial (but really good) Arduino support, an official MicroPython port, and a CircuitPython port. We of course recommend CircuitPython because we think it’s the easiest way to get started and it has support with most of our drivers, displays, sensors, and more, supported out of the box so you can follow along with our CircuitPython projects and tutorials.
Pinout and shape is Seeed Xiao compatible, with castellated pads so you can solder it to a PCB with a cut out to allow the bottom components some breathing room. In addition to the QT connector, we also added an RGB NeoPixel (with a controllable power pin to allow for ultra-low-power usage), and both boot-mode and reset buttons (great for restarting your program or entering the bootloader). This QT Py comes with loose 0.1” headers you can solder in for breadboard use.
While the RP2040 has lots of onboard RAM (264KB), it does not have built-in FLASH memory. Instead, that is provided by the external QSPI flash chip. On this board there is 4MB, which is shared between the program it’s running and any file storage used by MicroPython or CircuitPython. When using C/C++ you get the whole flash memory, if using Python you will have about 3 MB remaining for code, files, images, fonts, etc.
Inside the RP2040 is a ‘permanent ROM’ USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOT button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar - we use the technique on all our native-USB boards. Just note you don’t double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!
The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit or DSP hardware support - so if you’re doing something with heavy floating point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you’ll get close-to-M4 speeds!
For peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).
You’ll note there’s no I2S peripheral, or SDIO, or camera, what’s up with that? Well, instead of having specific hardware support for serial-data-like peripherals like these, the RP2040 comes with the PIO state machine system which is a unique and powerful way to create custom hardware logic and data processing blocks that run on their own without taking up a CPU. For example, NeoPixels - often we bitbang the timing-specific protocol for these LEDs. For the RP2040, we instead use PIO object that reads in the data buffer and clocks out the right bitstream with perfect accuracy. Same with I2S audio in or out, LED matrix displays, 8-bit or SPI based TFTs, even VGA! In MicroPython and CircuitPython you can create PIO control commands to script the peripheral and load it in at runtime. There are 2 PIO peripherals with 4 state machines each.
There’s a few things everyone loves: ice cream, kittens, and honkin’ large TFT screens. We’re no strangers to small TFT’s - from our itsy 1.14” color display that graces many-a-TFT-Feather to our fancy 3.5” 320x480 breakout screen. But most people who dabble or engineer with microcontrollers know that you sort of ‘top out’ at 320x480 - that’s the largest resolution you can use with every day SPI or 8-bit 8080 interfaces. After that, you’re in TTL-interface TFT land, where displays no longer have an internal memory buffer and instead the controller has to continuously write scanline data over a 16 or 18 or 24 pin interface.
RGB TTL interface TFT displays can get big: they start out at around 4.3” diagonal 480x272, and can get to 800x480, 800x600 or even 720x720. For displays that big, you need a lot of video RAM (800x480 at 24 bit color is just over 1MB), plenty of spare GPIO to dedicate, and a peripheral that will DMA the video RAM out to the display continuously. This is a setup familiar to people working with hefty microcontrollers or microcomputers, the sort of device that run cell phones, or your car’s GPS navigation screen. But until now, nearly impossible to use on low cost microcontrollers.
The ESP32-S3 is the first low-cost microcontroller that has a built in peripheral that can drive TTL displays, and can come with enough PSRAM to buffer those large images. For example, on the Adafruit Qualia ESP32-S3 for TTL RGB-666 Displays, we use a S3 module with 16 MB of Flash and 8 MB of octal PSRAM. Using the built in RGB display peripheral you can display graphics, images, animations or even video (cinepak, natch!) with near-instantaneous updates since the whole screen gets updated every ~30FPS.
This dev board is designed to make it easy for you to explore displays that use the “secondary standard’ 40-pin RGB-666 connector. This pin order is most commonly seen on square, round and bar displays. You’ll want to compare the display you’re using to this datasheet, if it matches you’ll probably be good! One nice thing about this connector ordering is that it also includes pins for capacitive touch overlay, and we wire those up to the ESP32-S3’s I2C port so you can also have touch control with your display.
Don’t forget! This is just the development board, a display is not included. Use any RGB-666 pinout display with or without a touch overlay. Note that you will need to program in the driver initialization code, dimensions, and pulse widths in your programming language. Here are some known-working displays that you can use in Arduino or CircuitPython:
On the Qualia board we have the S3 modules, with 16 pins connected to the TFT for 5-6-5 RGB color, plus HSync, VSync, Data Enable and Pixel Clock. There’s a constant current backlight control circuit using the TPS61169 which can get up to 30V forward voltage and can be configured for 25mA-200mA in 25mA increments (default is 25mA). Power and programming is provided over a USB C connector, wired to the S3’s native USB port. For debugging, the hardware UART TX pin is available as well.
Since almost every GPIO is used, and almost all RGB-666 displays need to be initialized over SPI, we put a PCA9554 I/O expander on the shared I2C bus. Arduino or CircuitPython can be instructed on how to use the expander to reset and init the display you have if necessary. The remaining expander pins are connected to two right-angle buttons, and the display backlight.
The expander is what lets us have a full 4-pin SPI port and two more analog GPIO pins - enough to wire up an MMC in 1-wire SDIO mode along with an I2S amplifier to make an A/V playback demo. Maybe we can even eat ice cream while watching kitten vids! There is also the shared I2C port, we provide a Stemma QT / Qwiic port for easy addition of any sensor or device you like.
It’s half USB Key, half Adafruit Trinket, half rotary encoder…it’s Rotary Trinkey, the circuit board with a Trinket M0 heart, a NeoPixel glow, and a rotary encoder body. We were inspired by this project from TodBot where a rotary encoder was soldered onto a QT Py. So we thought, hey what if we made something like that that plugs right into your computer’s USB port, with a fully programmable color NeoPixel? And this is what we came up with!
The PCB is designed to slip into any USB A port on a computer or laptop. There’s an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. Three pins of the microcontroller connects to a rotary encoder with built-in push switch. Another connects to a NeoPixel LED. Finally, one pin can be used as a capacitive touch input. A reset button lets you enter bootloader mode if necessary. That’s it!
Rotary encoders are soooo much fun! Twist em this way, then twist them that way. Unlike potentiometers, they go all the way around, and often have little detents for tactile feedback. But, if you just want to add one to your computer, you know its a real pain. This board is designed to make it very easy.
The SAMD21 can run CircuitPython or Arduino very nicely - with existing Rotary, NeoPixel and our FreeTouch libraries for the capacitive touch input. Over the USB connection you can have serial, MIDI or HID connectivity. The Rotary Trinkey is perfect for simple projects that use a rotating user input and underlit colorful output. Maybe you’ll set it up as a volume knob, scroll wheel, or zoom macro tool - whatever you like!
Please note this board DOES NOT come with a rotary encoder soldered in - we expect folks to pick their favorite rotary encoder and knob! Five solder points and you’re done.
We think it’s just an adorable little board, small and durable and inexpensive enough that it could be a first microcontroller board or inspiration for advanced developers to make something simple and fun.
It’s half USB Key, half temperature-humidity sensor… it’s the Adafruit SHT41 and SHT45 Trinkey boards. We wanted to make it super-easy to add one of our most popular combination environmental sensors to any computer with a USB A port.
The PCB is designed to slip into any USB A port on a computer or laptop. There’s an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to a NeoPixel LED. Another pin is used as a capacitive touch input on the end. A reset button lets you enter bootloader mode if necessary. That’s it!
The SAMD21 can run CircuitPython or Arduino nicely - both have existing SHT4x, NeoPixel, and our FreeTouch (capacitive touch) libraries. Over the USB connection, you can have serial, MIDI, or HID connectivity.
The SHT41 sensor is the fourth generation of I2C temperature and humidity sensor from Sensirion. (They started at the SHT10 and reached the top!). The SHT41 has an excellent ±1.8% typical relative humidity accuracy from 25 to 75% and ±0.2 °C typical accuracy from 0 to 75 °C. The reported temperature may be a few degrees higher than ambient due to self-heating.
The SHT45 sensor is the fourth generation (started at the SHT10 and worked its way up to the top!). The SHT45 has an excellent ±1.0% typical relative humidity accuracy from 25 to 75% and ±0.1°C typical accuracy from 0 to 75 °C. The reported temperature may be a few degrees higher than ambient due to self-heating.
The SHT41 or SHT45 Trinkey is perfect for simple projects that want to read the ambient temperature and humidity without extra wiring, soldering, drivers, or complex software. We even ship the board pre-programmed with code that will print a unique serial number, the temperature, humidity, and touch sensor over a serial/COM port in CSV (comma-separated value) format so you can use it immediately. If you need to measure farther than the computer port, simply use any USB A extension cable.
If you don’t need high precision, save a few $ with the SHT41 Trinkey, which has ±1.8% typical relative humidity accuracy from 25 to 75% and ±0.2°C typical accuracy from 0 to 75 °C.
We think it’s just an adorable little board. It’s small, durable, and inexpensive enough to be a first microcontroller board or an inspiration for advanced developers to make something simple and fun.
It’s half USB Key, half Adafruit Trinket, half mini slide pot… it’s Slider Trinkey, the circuit board with a Trinket M0 heart, NeoPixel glow, and a 35mm long 10KΩ slide potentiometer.
The PCB is designed to slip into any USB A port on a computer or laptop. There’s an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to the middle of the slide potentiometer as an analog input. Another connects to two NeoPixel LEDs. The third pin can be used as a capacitive touch input. A reset button lets you enter bootloader mode if necessary. That’s it!
The SAMD21 can run CircuitPython or Arduino very nicely - with existing NeoPixel and our FreeTouch libraries for the capacitive touch input. Over the USB connection, you can have serial, MIDI, or HID connectivity. The Slider Trinkey is perfect for simple projects that can use a few user inputs and colorful output. Maybe you’ll set it up as a monitor brightness adjuster, or volume control, or color picker.
Please note this board DOES come with a pre-soldered slide pot (there’s really only one that fits and we happen to stock it) Since we use a PCB with a USB A shape, its possible to accidentally yank the board out if you push the potentiometer all way way out and then keep pushing out. So be kind and careful with your Slider Trinkey! It isnt meant for yanking.
We think it’s just an adorable little board, small and durable and inexpensive enough that it could be a first microcontroller board, or inspiration for advanced developers to make something simple and fun.
Adafruit Sparkle Motion - All-In-One WLED and xLights Board
We’re designing a board for using WLED - and we want to make like the bestest board in the whole world. Our resident mermaid, firepixie makes a lot of projects with WLED and she loves it! So how can we make something that will be powerful but not too bulky? Here’s some things we’re thinking about asthe design starts to congeal like cranberry sauce:
The Adafruit Sparkle Motion Stick is part of our series of “Sparkle Motion” boards, which are our attempt to make the best small WLED-friendly smart LED driving board in the whole world. Our resident mermaid, firepixie makes a lot of projects with WLED, and she loves it! So, how can we make something powerful enough to drive advanced LED projects that need a compact design?
This version includes both the Sparkle Motion Stick and the enclosure, which is great if you want to protect your USB dongle from everyday usage, but note that it is not waterproof or weatherproof. There are three pieces: two snap over the PCB to capture it in place, and one can be used as a USB A port cap. We also like there’s a button lever - by default in WLED pin 0 is an on/off mode switcher, but you can program it to do other stuff.
The USB Stick version of the Sparkle Motion is a simpler version of our full-featured Sparkle Motion. It even fits into a low cost off-the-shelf case for protection.
Compared to our larger Sparkle Motion board, this only supports 5V and doesn’t have a reset button, there are fewer outputs, and no breakout pads of I2C/GPIO connections for external accessories.Compared to our Sparkle Motion Mini, this has a USB A port so it’s 2A max power. It does have IR and built-in terminal blocks but does not have GPIO breakout pads.
While we recommend it for use with WLED, it will also work just fine as a compact ESP32 board for use with Arduino, ESP-IDF, MicroPython, CircuitPython, or any other ESP32-supported codebase.
Coming soon from Adafruit, check out the weekly “Top Secret” segment on ASK AN ENGINEER or the upcoming new product videos on YouTube.
It’s half USB Key, half TRRS breakout… it’s the Adafruit TRRS Trinkey specifically designed for Assistive Technology hackers and creators as a simple and low cost, but also flexible and extendable AT device.
Many AT interface devices use 3.5mm audio jacks to create switches or variable inputs - often mono TS or stereo TRS plugs. On the TRRS Trinkey, we connect all 6 pins of a ‘switched’ TRRS jack - tip, ring 1, ring 2, sleeve and the tip switch plus ring 1 switch - to 6 GPIO pins on the microcontroller. That means we can not only detect when plugs are inserted but can change which pins are input, ground or even 3V power. With the use of a stereo/mic splitter, we can have up to 3 simple switches, or two analog potentiometers, or one of each! We particularly like this jack because it has two through-hole contacts near the opening for a good mechanical connection.
The PCB is designed to plug into any USB A port on a computer or laptop. There’s an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to a NeoPixel LED. A reset button lets you enter bootloader mode if necessary. The microcontroller can be programmed easily thanks to the UF2 bootloader and CircuitPython: simply drag-n-drop new code on.
The SAMD21 can run CircuitPython or Arduino nicely. Over the USB connection, you can have serial, MIDI, or HID keyboard/mouse connectivity. Because its a fully programmable chip, it’s possible to customize the keyboard or mouse commands executed on each button, or even set up chording patterns.

The module can work independently with a size of only 27 x 40.5 x 4.5mm, and a deep sleep current as low as 6mA.
ESP32-CAM can be widely used in various IoT applications, suitable for home smart devices, industrial wireless control, wireless monitoring, QR wireless identification, wireless positioning system signals and other IoT applications. It is an ideal solution for IoT applications.
ESP32-CAM adopts DIP package and can be used directly by plugging in the bottom plate, realizing the rapid production of products, providing customers with high-reliability connection methods, which is convenient for application in various IoT hardware terminal occasions.
Ultra-small 802.11b/g/n Wi-Fi + BT/BLE SoC module
The serial port on the ESP32-MB adapter which usually ships with these boards has the Serial Request-To-Send (RTS) hardware flow-control line physically connected to the ESP32 Reset (RST) pin, and it also has the Serial Data-Terminal-Ready (DTR) hardware flow-control line physically connected to the ESP32 GPIO pin.
This allows software which knows this (e.g. Arduino) to automatically perform hardware resets over the serial port by pulsing the RTS-line, and to automatically perform firmware updates by holding the DTR line low while pulsing the RTS line.
Unfortunately, many serial emulators and even some python libraries which communicate via Serial ports will typically set the state of one of both of these hardware flow control lines - this means that your ESP32-CAM might not be able to boot or be used by some software. Notable examples include Thonny, ampy, pyboard, and Windows version of Python itself*
* The work-around for Windows python is to first create the serial port object, without specifying which port to use - this bypasses the Python windows bug which always sets the RTS/DTR pins. You can then tell the serial object which port, and set the RTS/DTR pins as you like.

The Evo M51 is an FPGA-enhanced Feather compatible compute module from Alorium Technology that features a 32-bit SAMD51 microcontroller along with an Intel MAX 10 FPGA.
Designed for use as an embeddable system-on-module, all of the standard Feather I/O are also routed to castellated vias along the edge of the board. There are 34 additional castellated digital I/O connected to the FPGA and accessible via the SAMD51.
Most digital I/O connections are routed through the FPGA to and from the primary and castellated I/O. This provides the opportunity for developers to immediately capture inputs or drive outputs from the FPGA without requiring direct interaction with the SAMD controller.
Evo M51 will support Alorium Technology-supplied pre-built FPGA images that target specific application use cases. In addition, designers will have the option to develop their own custom logic blocks and integrate them into the top-level MAX 10 FPGA design.
Evo was specifically designed to support running CircuitPython. It is also programmable with Arduino just like many other boards based upon the SAMD51.
D13)In order to take full advantage of the additional I/O on Evo M51 using CircuitPython, we have created a custom library bundle that can be found on the Alorium Technology GitHub page:

The Black Lives Matter Education & Workshop Kit is an open-source design the Adafruit team published during the peaceful demonstrations for social justice in the summer of 2020 (https://github.com/adafruit/BLM-Badge-PCB). As a company and culture we came together to make our voices heard, share the pain we all had, the anger, and then work together for equality and justice in our communities (https://www.adafruit.com/blacklivesmatter). We listened to each other, we marched, we donated our time, resources, we distributed PPE at community events, we came together.
The kit is a snapshot in time, a time capsule of what we did together, and what we can build together going forward. The kit can be used for learn-to-code events remotely or in person when gatherings are safe post-COVID. We wanted to make something that would continue to emphasize the moment, is a movement.
The kits will never be for sale from Adafruit, they will be donated to learning-to-code organizations, social justice groups, and events.
This education and workshop kit is build around a Cortex M0+ processor that can run Arduino or CircuitPython.

The main controller of this board is the Nordic Semiconductor nRF52840 with 1MByte of FLASH memory and 256KByte of SRAM. The nRF52840 SoC is the most advanced member of the nRF52 Series. It meets the challenges of sophisticated applications that need protocol concurrency and a rich and varied set of peripherals and features. It offers generous memory availability for both Flash and RAM, which are prerequisites for such demanding applications.
The nRF52840 is fully multiprotocol capable with full protocol concurrency. It has protocol support for Bluetooth LE, Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT and 2.4 GHz proprietary stacks.
In the recent years we have noticed that we are seeing more and more USB Type C cable laying around the lab due to the fact that all new phones and accessories use them. As of yet we haven’t seen any shortage of micro USB cables but we are not getting any new ones any more and old ones do break occasionally. So we decided to go for a USB Type C connector for this board. A bonus of this is that they are quite bit more durable and you don’t have to fiddle with the cable before plugging it in.
The board is packed with hardware features, here’s a short list of its most prominent ones.
– Sturdy USB Type C connector– nRF52840 @ 64MHz– 1MB FLASH + 256KB RAM– 2 MByte of NOR FLASH memory– 32.768 KHz crystal for clock generation & RTC– 3.3V regulator with 600mA peak current output, most of which is reserved for the board itself– USB native support, comes with UF2 USB bootloader– 20 GPIO pins– Hardware Serial, hardware I2C, hardware SPI support– PWM outputs on all pins– 6 x 12-bit analog inputs– Built in 250mA lipoly charger with charging status indicator LED– Pin #13 red LED for general purpose blinking– Power/enable pin– 4 mounting holes– Reset button– Neopixel LED that indicates board status but that can be used by the programmer
The Challenger NB RP2040 WiFi is an Arduino/Micropython compatible Challenger NB (NB for No Battery) format micro controller board based on the Raspberry Pico chip. The Challenger NB form factor is based on Adafruits Feather format but we have removed the battery connector, LiPo charger and instead added a bunch of IO pins. It has retained most of the original Feather pinout so most (all) existing feather wings should work nicely with this board as well.
Just like the Challenger RP2040 WiFi it has a ESP8285 WiFi chip. For those of you that is unfamiliar with this device, it is basically an ESP8266 device with an integrated 1MByte of flash memory. This allows us to have an AT command interpreter inside this chip that the main controller can talk to and connect to you local WiFi network. The communications channel between the two devices is an unused UART on the main controller and the standard UART on the ESP8285. As simple as it can be.
The ESP8285 chip comes pre-flashed with Espressif’s AT command interpreter stored in the internal 1MByte of the ESP8285. This interpreter support most of the operating and sleep modes of the standard ESP8266 framework which makes it easy to work with. Talking to the device is as easy as opening the second serial port (Serial2), resetting the ESP8285 and start listening for events and sending commands.
The iLabs Challenger RP2040 LoRa is a small embedded computer equipped with a LoRa modem module on board, in the popular Adafruit Feather form factor. It is based on an RP2040 microcontroller from Raspberry Pi which is a dual-core Cortex M0 that can run on a clock up to 133MHz.
This is a spin-off from our Challenger RP2040 WiFi board but we have replaced the WiFi module with a low power RFM95W LoRa radio module from Hope RF. The transceiver features a LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
The RFM95W is connected to the microcontroller using an SPI channel and a few GPIO signals to handle signalling from the modem circuit. Besides the modem module, there is only one additional U.FL connector that forms the modem functionality. Simply hook your external antenna to this connector and you are ready to go.
We paired the RP2040 with 8MByte high-speed flash capable of supplying data up to the max speed. The flash memory can be used both to store instructions for the microcontroller as well as data in a file system and having a file system available makes it easy to store data in a structured and easy to program approach.
The device can be powered by a Lithium Polymer battery connected through a standard 2.0mm connector on the side of the board. An internal battery charging circuit allows you to charge your battery safely and quickly. The device is shipped with a programming resistor that sets the charging current to ~450mA. this resistor can be exchanged by the user to either increase or decrease the charging current, depending on the battery that is being used.
The Challenger RP2040 LTE is an Arduino/CircuitPython compatible Adafruit Feather format microcontroller board based on the Raspberry Pico chip.
This board has been designed with portable applications in mind. By using the powerful dual core RP2040 combined with 8Mbyte of flash memory, you get a device that can handle pretty much anything you can throw at it. For instance, if you let one core handle the LTE modem and the second core do all the UI stuff, you get an extremely responsive system. Not to mention that the 8 MByte of FLASH memory will let you install any (or all) CircuitPython support libraries that you will ever need.
The Challenger RP2040 SD/RTC is an Arduino/Circuitpython compatible Adafruit Feather format micro controller board based on the Raspberry Pico chip. This board is equipped with an micro SD card reader and a Real Time Clock making it super useful for data logging applications.
RP2040 is the debut micro controller from Raspberry Pi. It brings their signature values of high performance, low cost, and ease of use to the micro controller space. With a large on-chip memory, symmetric dual-core processor complex, deterministic bus fabric, and rich peripheral set augmented with our unique Programmable I/O (PIO) subsystem, RP2040 provides professional users with unrivaled power and flexibility. With detailed documentation, a polished Circuitpython port, and a UF2 boot loader in ROM, it has the lowest possible barrier to entry for beginner and hobbyist users
This board is equipped with a micro SD card connector that will house standard micro SD cards allowing your application to have many gigabytes of storage room for sensor data or what ever you want to place on it. Together with a fancy display you could also store cool images.
It is normally very useful to tag sensor data with a time stamp so we included a Real Time Clock chip to make this easy for you.
The chip we use is the MCP79410 general purpose I2C™Compatible real-time clock/calendar. It is a highly integrated real time clock with nonvolatile memory and many other advanced features. These features include a battery switchover circuit for backup power, a timestamp to log power failures and digital trimming for accuracy. Using a low-cost 32.768 kHz crystal or other clock source, time is tracked in either a 12-hour or 24-hour format with an AM/PM indicator and timing to the second, minute, hour, day of the week, day, month and year. As an interrupt or wakeup signal, a multifunction open drain output can be programmed as an Alarm Out or as a Clock Out that supports 4 selectable frequencies.
The intperrupt output from the RTC is connected to pin GPIO25 on the RP2040 and can be used to wake up the device repeatedly to collect data.
In the recent years we have noticed that we are seeing more and more USB Type C cable laying around the lab due to the fact that all new phones and accessories use them. As of yet we haven’t seen any shortage of micro USB cables but we are not getting any new ones any more and old ones do break occasionally. So we decided to go for a USB Type C connector for this board. A bonus of this is that they are quite bit more durable and you don’t have to fiddle with the cable when plugging it in.
The board is equipped with a standard 2.0mm JST connector for connecting a rechargeable LiPo battery. There is also an internal battery charger circuit that charges your battery as long as a USB cable is inserted or the VUSB connection is connected to 5V.
The Challenger RP2040 SubGHz board is an Arduino/Circuitpython compatible Adafruit Feather format micro controller board based on the Raspberry Pico (RP2040) chip.
This is a spin-off from our Challenger RP2040 LoRa board but in this case we replaced the LoRa module with a low power SubGHz radio module also from Hope RF. The transceiver features a proprietary long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
The RFM69HCW is a transceiver module capable of operation over a wide frequency range, including the 315,433,868 and 915MHz license-free ISM (Industry Scientific and Medical) frequency bands. Currently we are only supporting the 868 and 915MHz bands but this may change in the future. All major RF communication parameters are programmable and most of them can be dynamically set. The RFM69HCW offers the unique advantage of programmable narrow-band and wide- band communication modes.
The RFM69HCW is connected to the RP2040 via SPI channel 1 and a few GPIO’s that is required for signaling. A U.FL connector is used to attach your antenna to the board.
The Challenger RP2040 WiFi is an Arduino/Micropython compatible Adafruit Feather format micro controller board based on the Raspberry Pico chip.
When we designed this board we took our existing Challenger M0 WiFi board and replaced the SAMD21 micro controller with the much more powerful dual core RP2040 Cortex-M0 device. The RP2040 have two Cortex-M0 CPU cores clocked at 133 Mhz and 264 Kbyte SRAM integrated. On our board we decided to put a 8 MByte flash memory for your programs and file storage.
Just like the Challenger M0 WiFi it has a ESP8285 WiFi chip. For those of you that is unfamiliar with this device, it is basically an ESP8266 device with an integrated 1 MByte of flash memory. This allows us to have an AT command interpreter inside this chip that the main controller can talk to and connect to you local WiFi network.

board.D13 LED for basic blinkingCrickit is a Creative Robotics & Interactive Construction Kit. It’s an add-on for the popular Circuit Playground Express that lets you #MakeRobotFriend using CircuitPython (and more).
Bolt on a Circuit Playground using the included stand-off bolts and start controlling motors, servos, solenoids. With CRICKIT you also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends the Circuit Playground so you can still use all the goodies on the CPX, but now you have a robotics playground as well.
The Crickit is powered by seesaw, a I2C-to-whatever bridge firmware. So you only need to use two data pins to control the huge number of inputs and outputs on the Crickit. All those timers, PWMs, sensors are offloaded to the co-processor.
All are powered via 5 V DC, so you can use any 5V-powered servos, DC motors, steppers, solenoids, relays etc. To keep things simple and safe, CRIKIT does not support mixing voltages, use only 5 V - not for use with 9 V or 12 V robotic components.

This is a great companion for our Circuit Playground Express or Bluefruit boards thanks to their fast SPI hardware speeds, and works in Arduino and CircuitPython. You can use it with the Circuit Playground Classic but it won’t be very fast, as you have to bitbang the SPI - and the display has a lot of pixels - so it’s not recommended.
Comes with a PCB that has pre-soldered standoffs attached, and 12x M3 screws for attachment. Fits all Circuit Playgrounds but like we mentioned earlier, the Express and Bluefruit are recommended.
We wanted to build some projects that have a small screen and a lot of sensors. This board has a 1.3″ 240×240 IPS TFT display, two buttons, and sensors.
Available sensors:
There’s a Qwiic/STEMMA QT connector for adding more sensors, like PM2.5 air quality and others that were too big to fit on the board.
We’ll be primarily using CircuitPython for programming it, but it will also work in Arduino.
After designing it, the board was close enough to micro:bit-shape-size that we moved a few parts to make it fit in micro:bit robots and some projects – the nrf52840 is a big upgrade chip and can do stuff like Tensorflow Lite for Microcontrollers, BLE central and peripheral, and more.

The microcontroller also uses less power than Linux Boards (although its of course a lot less powerful as well) so will run longer on battery power, it has loads of IO pins, and it can be used as an IO board for PCs, Macs, or Rasp Pis without having to program it first. Simply take the Espruino out of its packaging and get started!
NOTE: The Wifi of this board is based on ESP8266 and might not work with CircuitPython. CircuitPython typically use Airlift that rely on ESP32 with better support for TLS such as this breakout board.
The Adafruit Feather Bluefruit Sense takes our popular Feather nRF52840 Express and adds a smorgasbord of sensors to make a great wireless sensor platform. This Feather microcontroller comes with Bluetooth Low Energy and native USB support featuring the nRF52840! This Feather is an ‘all-in-one’ Arduino-compatible + Bluetooth Low Energy with built in USB plus battery charging. With native USB it works great with CircuitPython, too.
Like the Feather nRF52840, this chip comes with Arduino IDE support - you can program the nRF52840 chip directly to take full advantage of the Cortex-M4 processor, and then calling into the Nordic SoftDevice radio stack when you need to communicate over BLE. Since the underlying API and peripherals are the same for the ‘832 and ‘840, you can supercharge your older nRF52832 projects with the same exact code, with a single recompile!
This Feather is also a BLE-friendly CircuitPython board! CircuitPython works best with disk drive access, and this is the only BLE-plus-USB-native chip that has the memory to handle running a little Python interpreter. The massive RAM and speedy Cortex M4F chip make this a good match. Make centrals or peripherals with the ease of CircuitPython.
A chorus of supporting sensors surround the module so you can do all sorts of environmental and motion sensing:
Feather is a development board from Adafruit, and like its namesake it is thin, light, and lets you fly! Adafruit designed Feather to be a new open standard for portable microcontroller cores.
This is the Adafruit Feather M0 Adalogger - Adafruit’s take on an ‘all-in-one’ Cortex M0 datalogger (or data-reader) with built in USB and battery charging. It is an Adafruit Feather M0 with a microSD holder. Check out the other boards in the Feather family.
At the Feather M0’s heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3 V logic, the same one used in the new Arduino Zero. This chip has a whopping 256 KB of FLASH (8x more than the Atmega328 or 32u4) and 32 KB of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip.
To make it easy to use for portable projects, Adafruit added a connector for 3.7 V Lithium polymer batteries and built in battery charging. You don’t need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. The battery is tied thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.
The Feather M0 Adalogger uses the extra space left over to add MicroSD + a green LED:

The Adafruit Feather M0 Express was one of the first development boards designed for CircuitPython by Adafruit. Unlike the original Feather M0 Basic, it added a NeoPixel status LED and external 2 MB SPI Flash for storing CircuitPython code.
It is a great entry into the Feather ecosystem with CircuitPython. However, it is now out performed by the Feather M4 Express which has a faster microcontroller with more RAM. The additional RAM allows CircuitPython to load more code all at once than this Feather M0 Express can. Check out the other boards in the Feather family.
Crickit is Adafruit’s Creative Robotics & Interactive Construction Kit. It’s an add-on to popular Feather ecosystem boards that lets you #MakeRobotFriend using CircuitPython.
Plug in any Feather mainboard you want into the center, and you’re good to go! The Crickit is powered by seesaw, an I2C-to-whatever bridge firmware. So you only need to use two I2C data pins to control the huge number of inputs and outputs on the Crickit. All those timers, PWMs, sensors are offloaded to the co-processor.
The only thing that is not managed by seesaw is the audio output. Provided is a small jumper you can solder to connect the audio amplifier to the first analog pin. On Feather M0’s this is a true analog output (DAC) and you can play audio clips with CircuitPython. Other Feathers may not have a DAC! In that case, you can solder a wire to jumper the audio amp to a PWM pin.
You get to use all the non-I2C signal pins on your feather and get a boat-load of extra in/out pins, motor controllers, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your Feather so you can still use all the goodies, including stacking FeatherWings on top. But now you have a robotics playground as well.
All are powered via 5V DC, so you can use any 5V-powered servos, DC motors, steppers, solenoids, relays etc. To keep things simple and safe, we don’t support mixing voltages, so only 5V, not for use with 9V or 12V robotic components.
This is the Adafruit Feather M0 RFM69 Packet Radio (433, 868, or 915 MHz). Also called RadioFruits, Adafruit’s take on an microcontroller with a RFM69HCW packet radio transceiver plus built in USB and battery charging. Its an Adafruit Feather M0 with a VHF radio module cooked in!

The Feather M0 Radio uses the extra space left over to add an RFM69HCW 433 or 900 MHz radio module. These radios are not good for transmitting audio or video, but they do work quite well for small data packet transmission when you need more range than 2.4 GHz (BT, BLE, WiFi, ZigBee).
Comes fully assembled and tested, with a USB bootloader. Includes some headers so you can solder it in and plug into a solderless breadboard. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna.
This is the Adafruit Feather M0 RFM96 LoRa Radio (433 MHz). Also called RadioFruits, Adafruit’s take on an microcontroller with a “Long Range (LoRa)” packet radio transceiver with built in USB and battery charging. It is an Adafruit Feather M0 with a 433MHz radio module cooked in! Great for making wireless networks that are more flexible than Bluetooth LE and without the high power requirements of WiFi.

Like its SAMD51 cousin, the ATSAME51J19 comes with a 120 MHz Cortex M4 with floating point support and 512 KB Flash and 192 KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset for CAN interfacing projects.
At the end of the board we have placed a CAN transceiver chip as well as a 5 V converter to generate 5 V power to the transceiver even when running on battery. The two CAN signal lines and ground reference signal are available on a 3-pin 3.5 mm terminal block. The chip and booster can be put to sleep for power saving. The built-in CAN can read or write packets and has support in both Arduino and CircuitPython.
Like the original Feather M4 Express, you’ll find a Mini NeoPixel and 2 MB SPI Flash. When used in CircuitPython, the 2 MB flash acts as storage for all your scripts, libraries and files.
And best of all, it’s a Feather - so you know it will work with all our FeatherWings! What a great way to quickly get up and running. It’s even pin-compatible with the original Feather M4.
Easy reprogramming: the Feather M4 CAN comes pre-loaded with the UF2 bootloader, which looks like a USB storage key. Simply drag firmware on to program, no special tools or drivers needed! It can be used to load up CircuitPython or Arduino IDE (it is bossa-compatible).
Comes fully assembled and tested, with the UF2 USB bootloader. We also toss in some headers so you can solder it in and plug into a solderless breadboard.

The most exciting part of the Feather M4 is that while you can use it with the Arduino IDE - and it’s bonkers fast when you do, we are shipping it with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with main.py on it. Edit main.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can’t install software on. When you’re done, unplug the Feather and your code will go with you.

It is Adafruit’s take on an ‘all-in-one’ Bluetooth Low Energy device with built in USB plus battery charging. With native USB it’s part of the CircuitPython party.
This chip has twice the flash, and four times the SRAM of its earlier sibling, the nRF52832 - 1 MB of FLASH and 256KB of SRAM. Compared to the nRF51, this board has 4-8 times more of everything.
This is Adafruit’s first BLE-friendly CircuitPython board! CircuitPython works best with disk drive access, and this is the only BLE-plus-USB-native chip that has the memory to handle running the Python interpreter. The massive RAM and speedy Cortex M4F chip makes this a good match.
It’s got tons of peripherals: plenty of GPIO, analog inputs, PWM, timers, etc. Best of all, it’s got that native USB! Finally, no need for a separate USB serial chip like CP2104 or FT232.
Some other upgrades are an extra ‘USER’ switch that could be used to trigger OTA updates (or whatever you choose), a NeoPixel LED for status updates, 2 MB of QSPI Flash for storing CircuitPython files, and a SWD connector.
Comes pre-programed the chip with a UF2 bootloader, which can use either command line UART programming with nrfutil or drag-n-drop mass storage, for CircuitPython installation and also because mass-storage-drive bootloaders make updating firmware so easy. Want to program the chip directly? You can use command line tools with your favorite editor and toolchain. If you want to use an SWD programmer/debugger (for even more advanced usage), use a standard 2x5 0.05” connector.

Only 13mm long, Fomu really puts the micro in microprocessor. Fomu is a fully open-source, programmable FPGA device that sits inside a USB Type-A port. It has four buttons, an RGB LED, and an FPGA that is compatible with a fully open source chain and capable of running a RISC-V core. Fomu comes in a custom plastic enclosure that slots perfectly into a USB port.
Fomu:
For example, many embedded projects use WS2812 LEDs such as NeoPixels that require a specialized timing signal. A CPU can generate this signal in software, but it can’t do anything in the background while talking to the light. If the string of LEDs is very long, then the CPU wastes a lot of time and power generating the signal.
With an FPGA, it becomes possible to create an “LED driver” that allows the CPU to keep running while a hardware component handles the timing. The CPU could do other work, or could put itself in a low power state.
In fact, the “CPU” in the FPGA is created from a hardware description language, meaning it can be modified or swapped out. If you wanted, you could create a brand-new CPU instruction. Do you want to have fast 64-bit multiplies? Or maybe you want a way to get random numbers easily? With Fomu and its FPGA, you have the source code to the CPU itself.

Are you the kind of person who doesn’t like taking down the skeletons and spiders until after January? This is development board for you. This is electronics at its most spooky! The Adafruit HalloWing is a skull-shaped ATSAMD21 board with a ton of extras built in to make for an adorable wearable, badge, development kit, or the engine for your next cosplay or prop.
On the front is a cute 1.44” sized 128x128 full color TFT. There’s also 4 fang-teeth below the display, these are analog/capacitive touch inputs with big alligator-clip holes.
On the reverse is a smorgasbord of electronic goodies:
Right now you can use the Hallowing similarly Feather M0 Express, it’s got the same chip although the pins have been rearranged. CircuitPython support, the extra 8 MB of SPI Flash is great for sound effects projects where you want to play up to 3 minutes of WAV files.
On each side of the Hallowing are JST-PH plugs for connecting external devices. The 3-pin JSTs connect to analog pins on the SAMD21, so you can use them for analog inputs. One is labeled for Neopixel and one for Sensors since most people will have one of each. The 4-pin JST connector connects to the I2C port and you can fit Grove connectors in it for additional hardware support.
Comes fully assembled and ready to be your spooky friend. Comes installed with the UF2 bootloader.

M5Stack’s Timer Camera X is an all-in-one camera module based on ESP32, integrated with ESP32 chip and has 8M PSRAM. Why so much PSRAM? Well, the camera can shoot up to 2048x1536 resolution photos(!). The module also comes with a built-in 140mAh battery and LED status indicator. There is a reset button under the LED.
You can use the built-in RTC (BM8563) to keep track of time to create custom, specific sleep and wake-up schedules. In deep sleep, the standby current of the entire Camera X can be as low as 10 μA. This camera supports sending images through WiFi and via the USB serial debug port. The bottom HY2.0-4P I2C port output can be connected to other I2C peripherals such as Grove or Stemma QT devices when this cable is in use.
A friendly heads-up: The low-power power management used by the Timer Camera series is different from the CORE and StickC devices. When in use, the PWR button is used as a power-on button (long press 2 seconds). If you need to shut down the device, use the software API or press the Reset button on the PCB.
Note: as 2025-07-07 there is no documented way to use the camera. Examples using espcamera produce initialization errors.

Folks love our wide selection of RGB matrices and accessories, for making custom colorful LED displays… and our RGB Matrix Shields and FeatherWings can be quickly soldered together to make the wiring much easier. But what if we made it even easier than that? Like, no solder, no wiring, just instant plug-and-play? Dream no more - with the Adafruit Matrix Portal add-on for RGB Matrices, there’s never been an easier way to create powerful Internet-connected LED displays.
Plug directly into the back of any HUB-75 compatible display (all the ones we stock will work) from 16x32 up to 64x64! Use the included screws to attach the power cable to the power plugs with a common screwdriver, then power it with any USB C power supply. (For larger projects, power the matrices with a separate 5V power adapter)
Then code up your project in CircuitPython or Arduino, our Protomatter matrix library works great on the SAMD51 chipset, knowing that you’ve got the wiring and level shifting all handled.
The Matrix Portal uses an ATMEL (Microchip) ATSAMD51J19, and an Espressif ESP32 Wi-Fi coprocessor with TLS/SSL support built-in. The M4 and ESP32 are a great couple - and each bring their own strengths to this board. The SAMD51 M4 has native USB so it can show up like a disk drive, act as a MIDI or HID keyboard/mouse, and of course bootload and debug over a serial port. It also has DACs, ADC, PWM, and tons of GPIO, so it can handle the high speed updating of the RGB matrix.
Meanwhile, the ESP32 has secure WiFi capabilities, and plenty of Flash and RAM to buffer sockets. By letting the ESP32 focus on the complex TLS/SSL computation and socket buffering, it frees up the SAMD51 to act as the user interface. You get a great programming experience thanks to the native USB with files available for drag-n-drop, and you don’t have to spend a ton of processor time and memory to do SSL encryption/decryption and certificate management. It’s the best of both worlds!
Comes with one fully-programmed and assembled MatrixPortal, preprogrammed with a rainbow digital sand demo for 32x64 LED matrices.

It’s half USB Key, half Adafruit Trinket…it’s Neo Trinkey, the circuit board with a Trinket M0 heart and four RGB NeoPixels for customizable glow. We were inspired by some USB key flashlight boards that would turn any battery pack into an LED torch. So we thought, hey what if we made something like that but with fully programmable color NeoPixels? And this is what we came up with!
The PCB is designed to slip into any USB A port on a computer or laptop. There’s an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to the four NeoPixel LEDs. Two other pins are used as capacitive touch inputs on the end - if you look carefully you can see the slotted end has left and right touch pads. A reset button lets you enter bootloader mode if necessary. That’s it!
The SAMD21 can run CircuitPython or Arduino very nicely - with existing NeoPixel and our FreeTouch libraries for the capacitive touch input. Over the USB connection you can have serial, MIDI or HID connectivity. The Neo Trinkey is perfect for simple projects that can use a few user inputs and colorful outputs. Maybe you’ll set it up as a simple status notifier, or stretch-break timer, or a macro keypad, or a random color generator, or, hey you could still make it into an LED flashlight if you wanted!
We think its just an adorable little board, small and durable and inexpensive enough that it could be a first microcontroller board, or inspiration for advanced developers to make something simple and fun.

There’s also a battery connector so you can power it without annoying trailing wires, and some neato power saving features that mean you can run it from batteries for ages.
Here are some things we reckon this mahoosive Inky would be great for:
Our new Pico W Aboard products come with a built in Raspberry Pi Pico W. This means you get all the advantages of a RP2040 microcontroller - a speedy fast dual-core ARM processor, a dynamic, growing ecosystem and a choice of different programming methods to experiment with. Most excitingly though, Pico W has wireless connectivity, so your Pico/RP2040 devices can communicate with each other, and the internet
Enter the (LED) matrix with Interstate 75 - a RP2040-powered driver board for HUB75-style RGB matrices, designed to plug neatly into the back of a LED panel. It provides a quick and easy way to whip up some scrolling signage or an eye-catching LED display for sensor outputs.
Raspberry Pi’s RP2040 microcontroller is a dual core ARM Cortex M0+ running at up to 133Mhz. It bundles in 264kB of SRAM, 30 multifunction GPIO pins (including a four channel 12-bit ADC), a heap of standard peripherals (I2C, SPI, UART, PWM, clocks, etc), and USB support.
One very exciting feature of RP2040 is the programmable IOs which allow you to execute custom programs that can manipulate GPIO pins and transfer data between peripherals - they can offload tasks that require high data transfer rates or precise timing that traditionally would have required a lot of heavy lifting from the CPU.
A luxe 16 key USB-C keyboard with tactile mechanical switches and fully customisable RGB lighting, ideal for custom macro pads, midi controllers and stream decks. RP2040 gives Keybow 2040 low latency input, zero boot time and a new, compact footprint.

A compact 4 channel motor+encoder controller, powered by RP2040. It has RGB and per-motor indicator LEDs plus built in voltage and current sensing. There’s also a Qwiic/STEMMA QT connector for adding breakouts!
Motor 2040 can be powered either by plugging the board into a USB-C power source (like a PC or power adapter) or by connecting a battery pack to the EXT PWR or VSYS connections. On an unmodified board, you should only have one power source connected at a time, to avoid back-powering your computer or battery.
If you want to have two power sources connected at the same time, Motor 2040 has two traces on its underside that you can cut to do this safely.

A minimal but powerful RP2350 breakout board modelled on a Pin Grid Array, with the maximum exposed pins crammed into the smallest possible space.
PGA2350 is a compact RP2350 breakout designed to be embedded in projects where space is limited. It contains the components necessary to run the mighty RP2350B chip (that’s the crystal, regulator and essential support circuits), a beefy 8MB of PSRAM and a prodigious 16MB of flash storage. Note that it has no LEDs, buttons or USB connectors - you’ll need to attach your own USB connector to be able to program it.
All this drastic pruning means you get a small 25.4mm square footprint and a lot of exposed RP2350 pins to play with. 48 of them can be used as general purpose I/O (that’s eighteen more I/O than on a Raspberry Pi Pico!) and 8 are ADC-equipped. We’ve even managed to squeeze in some tiny pin labels to help identify them.
Header pins are sold separately - you can use standard Pico pin headers (though bear in mind you’ll need 64 pins if you want to populate it fully).
The RP2350 chip is the Double Quarter Pounder & Fries to the RP2040’s Double Cheeseburger and can have one or more RISC-V burgers instead of either of the M33 ARMs, to stretch the metaphor.
In addition to the modern M33 ARM cores, there are sides of: more PIO capability, a variety of low power states for sipping electrons, a whole security system and some sprinklings of specialist digital video circuits to offload DVI/HDMI output.
You can expect a tasty boost in performance - our “real world” MicroPython tests are running up to 2x faster compared to RP2040, and floating point number crunching in C/C++ is up to 20x faster. The extra on-chip RAM will make a big difference when performing memory intensive operations (such as working with higher resolution displays) and even more can be added thanks to external PSRAM support.
RP2350 comes in two flavours - A (standard) and B (all the pins). The B chip has a stonking 48 usable GPIO pins, including 8 ADCs and 24 PWMs, and features on some of our new products.

The pIRkey adds an IR remote receiver to any computer, laptop, tablet…any computer or device with a USB port that can use a keyboard. This little board slides into any USB A port, and shows up as an every-day USB keyboard. The onboard ATSAMD21 microcontroller listens for IR remote signals and converts them to keypresses, mouse movements, or even USB serial output.
Infrared is a favorite wireless protocol - no antennas, certifications, pairings, passwords, or special tools required. Works everywhere in the world and very intuitive - everyone’s got an IR remote in their home.
The pIRkey is an improvement on Adafruit’s original IRkey product, by adding a p for python. Now with CircuitPython being available for the tiny ATSAMD21E processor, it’s swapped in for the ATtiny85, giving a huge boost in power and a working Python interpreter on board as well. This means it is easy to reprogram, customize or adapt it to whatever Infrared-reading needs you may have.
When you plug it in, the pIRkey shows up as a triple device: USB disk drive to store code, USB serial for debugging and Python interactive command line, and USB keyboard/mouse that can transmit keypresses or mouse movements.
By default it ships with simple example code to read NEC remotes but you can use any remote that has about 38KHz output frequency which is the vast majority of remote controls. CircuitPython makes this all very easy to customize and adapt to your own needs.

The PROVES Kit blends Open-Source Hardware and Software. The Hardware developed includes the entire educational satellite structure, brackets, and printed circuit boards. One of the major issues that we sought to solve with the kit was to develop a single solution for an end to end space mission engineering education. Many other open source projects avalible to the community only feature a single element, like just a radio or just a flight computer.

The Adafruit PyBadge an all-in-one compact dev board programmable in CircuitPython. Full of features squeezed onto a 3 3⁄8 × 2 1⁄8 inch rounded credit card sized rectangle. It’s a perfect wearable badge, but can be used for many projects.
The PyBadge is powered by our favorite microcontroller, the ATSAMD51, with 512KB of flash and 192KB of RAM. There is an additional 2 MB of QSPI flash for file storage, handy for images, fonts, sounds, or game assets.
On the front, there is a 1.8” 160x128 color TFT display with dimmable backlight. There is fast DMA support for drawing, so updates are incredibly fast. There are also 8 silicone-top buttons: they are clicky but have a soft button top so they’re nice and grippy. The buttons are arranged to mimic a gaming handheld, with a d-pad, 2 menu-select buttons and 2 fire-action buttons. There are also 5 NeoPixel LEDs to dazzle or track activity.
On the back, there is a full Feather-compatible header socket set, so you can plug in any FeatherWing to expand the capabilities of the PyBadge. There are also 3 STEMMA connectors - two 3-pin with ADC/PWM capability and one 4-pin that connects to I2C - you can use this for Grove sensors as well.
For built-in sensors, there is a light sensor that points out the front, and a 3-axis accelerometer that can detect taps and free-fall. To make bleeps and bloops, there’s a built in buzzer-speaker. For projects where you need more volume, you can plug in an 8 ohm speaker.
You can power the PyBadge from any of Adafruit’s LiPoly batteries, but this 400mAh one is suggested. An on-off switch will save battery power when not in use. Or power the board from the Micro USB port - it will also charge the battery if one is attached.

The Adafruit PyGamer is an entry-level gaming handheld for DIY gaming and maybe a little retro-emulation, all in one compact dev board.
The PyGamer is powered by the ATSAMD51 microcontroller with 512KB of flash and 192KB of RAM. There is an additional 8 MB of QSPI flash for file storage, handy for images, fonts, sounds, or game assets.
On the front, you get a 1.8” 160x128 color TFT display with a dimmable backlight. There is fast DMA support for drawing - screen updates are incredibly fast. A dual-potentiometer analog stick gives great control, with easy diagonal movement, or really any direction you like.There are also 4 square-top buttons which fit square top button caps (available separately). The buttons are arranged to mimic a gaming handheld, with 2 menu-select buttons and 2 fire-action buttons. There are also 5 NeoPixel LEDs below the LCD screen to dazzle or track activity.
On the back, there is a full Feather-compatible header socket set to allow plugging in any FeatherWing, providinge expansion of the PyGamer’s capabilities. There are 3 integrated STEMMA connectors: two 3-pin with ADC/PWM capability and one 4-pin that connects to I2C - this can be used for Grove sensors as well.
For built in sensors, there’s a light sensor that points out the front, and a 3-axis accelerometer that can detect taps and free-fall. To make bleeps and bloops, plug in any set of stereo headphones. For projects where you need more volume, you can plug in an 8 ohm speaker. The PyGamer will auto-switch to speakers when they’re plugged in.
You can power the PyGamer from any Adafruit LiPoly battery, but this 350mAh one is suggested as it will fit into the Adafruit PyGamer acrylic case (sold separately). An on-off switch will save battery power when not in use. Or power the PyGamer from the Micro USB port - it will also charge up the battery if one is attached.

The PyPortal uses an ATMEL (Microchip) ATSAMD51J20, and an Espressif ESP32 Wi-Fi coprocessor with TLS/SSL support built-in. PyPortal has a 3.2″ 320 x 240 color TFT with resistive touch screen. PyPortal includes: speaker, light sensor, temperature sensor, NeoPixel, microSD card slot, 8MB flash, plug-in ports for I2C and 2 analog/digital pins, 3D files for custom enclosures / lanyard fastening. Open-source hardware, and Open-Source software, and CircuitPython. The device shows up as a USB drive and the code (Python) can be edited in any IDE, text editor, etc.
The M4 and ESP32 are a great couple - and each bring their own strengths to this board. The SAMD51 M4 has native USB so it can show up like a disk drive, act as a MIDI or HID keyboard/mouse, and of course bootload and debug over a serial port. It also has DACs, ADC, PWM, and tons of GPIO. Meanwhile, the ESP32 has secure WiFi capabilities, and plenty of Flash and RAM to buffer sockets. By letting the ESP32 focus on the complex TLS/SSL computation and socket buffering, it frees up the SAMD51 to act as the user interface. You get a great programming experience thanks to the native USB with files available for drag-n-drop, and you don’t have to spend a ton of processor time and memory to do SSL encryption/decryption and certificate management. It’s the best of both worlds!
The PyPortal Pynt is the little sister to our popular PyPortal - zapped with a shink ray to take the design from a 3.2” diagonal down to 2.4” diagonal screen - but otherwise the same!

Compared to the original PyPortal, the Pynt does not include a ADT7410 temperature sensor. Other than the ADT7410, the Pynt’s display, processor, STEMMA conectors and WiFi have the exact same wiring as the original 3.2” PyPortal so all Arduino/CircuitPython code will run exactly the same - just smaller!

The Titano uses an ATMEL (Microchip) ATSAMD51J20, and an Espressif ESP32 Wi-Fi coprocessor with TLS/SSL support built-in. PyPortal has a bigger 3.5″ diagonal 320 x 480 color TFT with resistive touch screen. Compare that to the original PyPortal’s 3.2” 240x320, we have twice as many pixels! Also, we’ve updated the connector to be a reverse-friendly USB C connector.
Compared to the original PyPortal, the Titano does not include a ADT7410 temperature sensor. It also has a higher-resolution screen with a different controller chip. The Processor, STEMMA conectors and WiFi have the exact same wiring as the original 3.2” PyPortal so if you are running Arduino/CircuitPython code, you’ll just have to adjust your graphics and fonts for the larger resolution screen!

CircuitPython rules! The PyRuler is the first ruler to be able to run CircuitPython. It features an embedded Adafruit Trinket M0, which is a tiny microcontroller board, built around the Atmel ATSAMD21E18 powerhouse.
The first time you soldered up a surface mount component you may have been surprised “these are really small parts!” and there’s dozens of different names too! QFN, TDFN, SOIC, SOP, J-Lead, what do they mean and how can you tell how big they are? On the reverse side of the PyRuler, just like with our PCB ruler, you have a reference board right at your fingertips.
While you can use the PyRuler with the Arduino IDE, it ships with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with code.py on it. Edit code.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can’t install software on. When you’re done, unplug the Trinket M0 and your code will go with you. CircuitPython is easier to code but not as low-level and complete as Arduino.
Note: If you soldered the optional SOIC-8 SPI Flash chip on to your QT Py, see the “QT Py Haxpress” page to make use of the extra space!
What a cutie pie! Or is it… a QT Py? This diminutive dev board comes with our favorite lil chip, the SAMD21 (as made famous in our GEMMA M0 and Trinket M0 boards).
This time it comes with our favorite connector - the STEMMA QT, a chainable I2C port that can be used with any of our STEMMA QT sensors and accessories.
OLEDs! Inertial Measurment Units! Sensors a-plenty. All plug-and-play thanks to the innovative chainable design: SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so you don’t even need to solder! Just plug in a compatible cable and attach it to your MCU of choice, and you’re ready to load up some software and measure some light.
Use any SparkFun Qwiic boards! Seeed Grove I2C boards will also work with this adapter cable.
Pinout and shape is Seeed Xiao compatible, with castellated pads so you can solder it flat to a PCB. In addition to the QT connector, we also added an RGB NeoPixel (with controllable power pin to allow for ultra-low-power usage), and a reset button (great for restarting your program, or entering the bootloader)
Runs Arduino like a dream, and can be used for basic CircuitPython projects. For more advanced usage like datalogging or file storage, solder an SOIC SPI flash chip onto the bottom pads,

A1A0 is analog out, A1 is not PWM capable)The Raspberry Pi foundation changed single-board computing when they released the Raspberry Pi computer, now they’re ready to do the same for microcontrollers with the release of the brand new Raspberry Pi Pico. This low-cost microcontroller board features a powerful new chip, the RP2040, and all the fixin’s to get started with embedded electronics projects at a stress-free price.
The Pico is 0.825” x 2” and can have headers soldered in for use in a breadboard or perfboard, or can be soldered directly onto a PCB with the castellated pads. There’s 20 pads on each side, with groups of general purpose input-and-output (GPIO) pins interleaved with plenty of ground pins. All of the GPIO pins are 3.3V logic, and are not 5V-safe so stick to 3V! You get a total of 26 GPIO pins, 3 of those can be analog inputs (the chip has 4 ADC but one is not broken out). There are no true analog output (DAC) pins.
On the slim green board is minimal circuitry to get you going: A 5V to 3.3V power supply converter, single green LED on GP25, boot select button, RP2040 chip with dual-core Cortex M0, 2 MegaBytes of QSPI flash storage, and crystal.
Inside the RP2040 is a ‘permanent ROM’ USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar - we use the technique all our native-USB boards. Just note you don’t double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!
The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit, or DSP hardware support - so if you’re doing something with heavy floating point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you’ll get close-to-M4 speeds!
For peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).
You’ll note there’s no I2S peripheral, or SDIO, or camera, what’s up with that? Well instead of having specific hardware support for serial-data-like peripherals like these, the RP2040 comes with the PIO state machine system which is a unique and powerful way to create custom hardware logic and data processing blocks that run on their own without taking up a CPU. For example, NeoPixels - often we bitbang the timing-specific protocol for these LEDs. For the RP2040, we instead use a PIO object that reads in the data buffer and clocks out the right bitstream with perfect accuracy. Same with I2S audio in or out, LED matrix displays, 8-bit or SPI based TFTs, even VGA! In MicroPython and CircuitPython you can create PIO control commands to script the peripheral and load it in at runtime. There are 2 PIO peripherals with 4 state machines each.
There is great C/C++ support, unofficial (but really good) Arduino support an official MicroPython port, and a CircuitPython port! We of course recommend CircuitPython because we think its the easiest way to get started and it has support with most our drivers, displays, sensors, and more, supported out of the box so you can follow along with our CircuitPython projects and tutorials.
While the RP2040 has lots of onboard RAM (264KB), it does not have built in FLASH memory. Instead that is provided by the external QSPI flash chip. On this board there is 2MB, which is shared between the program its running and any file storage used by MicroPython or CircuitPython. When using C/C++ you get the whole flash memory, if using Python you will have about 1 MB remaining for code, files, images, fonts, etc.

Raspberry Pi Pico 2 is Raspberry Pi Foundation’s update to their popular RP2040-based Pico board, now built on RP2350: their new high-performance, secure microcontroller. With a higher core clock speed, double the on-chip SRAM (512KB), double the on-board flash memory (4MB!), more powerful Arm M33 cores, new security and low-power features, and upgraded interfacing capabilities, the Raspberry Pi Pico 2 delivers a significant performance and feature boost while retaining hardware and software compatibility with earlier members of the Raspberry Pi Pico series.
The unique dual-core, dual-architecture capability of RP2350 allows users to choose between a pair of industry-standard Arm Cortex-M33 cores and a pair of open-hardware Hazard3 RISC-V cores. You can use either Arm or RISC-V cores, so this is a great way to dabble in RISC-V development with an affordable board that has lots of peripherals. The M33 has an FPU, and is ‘basically’ 2x as fast as the M0+ of the RP2040 when we speed-tested it.
Not only is the Pico 2 twice as fast, it has twice as much RAM, 520KB compared to 264KB. The Pico also has twice as much FLASH memory, 4MB instead of 2MB, which will make it a much better board for CircuitPython usage where the internal memory is used to store files. There’s also one more PIO blocks (3 blocks with 4 state machines apiece, rather than 2) so you can do even more pin twiddling at once. For folks who want to use the RP2350 to generate high frequency output signals like DVI display output, you can use the HSTX (high speed transmission) peripheral rather than PIO.
For customers who wanted a more secure microcontroller for product design, the RP2350 provides a comprehensive security architecture, built around Arm TrustZone for Cortex-M, and incorporating signed boot, 8KB of antifuse OTP for key storage, SHA-256 acceleration, a hardware TRNG, and fast glitch detectors. These features, including the secure boot ROM, are extensively documented and available to all users without restriction: this transparent approach, which contrasts with the “security throughobscurity” offered by legacy vendors, allows professional users to integrate RP2350, and Raspberry Pi Pico 2, into products with confidence.
Programmable in C / C++ and CircuitPython/MicroPython, and with detailed documentation, Raspberry Pi Pico 2 is the ideal microcontroller board for enthusiasts and professional developers alike. It makes an excellent upgrade to the RP2040, with lots of back-compatibility and some excellent upgrades.

Please note: The Pico 2Wcomes with the A2 version of the RP2350, which is affected by the E9 erratum. This erratum affects some uses of GPIO and PIO such as high-impedance inputs and the internal pulldowns. You may need to use 8.2K or smaller resistors if pull-downs are required. At this time, Sept 9 2024, there is no other version of the RP2350 available - only the A2 version.

Raspberry Pi Pico W brings WiFi + BLE wireless networking to the Pico platform while retaining complete pin compatibility with its older sibling.(BLE is not currently available on CircuitPython.)
Raspberry Pi Pico W is just like the classic Pico but adds on-board single-band 2.4GHz wireless interfaces (802.11n) using the Infineon CYW43439 while retaining the Pico form factor. The on-board 2.4GHz wireless interface has the following features:
Due to pin limitations (the Pico brings out all the GPIO) some of the wireless interface pins are shared with the exposed pads:
For best wireless performance, the antenna should be in free space. For instance, putting metal under or close by the antenna can reduce its performance both in terms of gain and bandwidth. Adding grounded metal to the sides of the antenna can improve the antenna’s bandwidth.
The Pico W is 51mm × 21mm × 1mm and can have headers soldered in for use in a breadboard or perfboard, or can be soldered directly onto a PCB with the castellated pads.

NOTE: This build is alpha quality and is for experimental use. It is missing features and has known issues.
The Raspberry Pi Compute Module 4 is based on the Raspberry Pi 4 Model B, but in a smaller form factor - perfect for embedding into products or projects without the bulk of a classic Raspberry Pi. You get all the computational power of Raspberry Pi 4 in a compact form factor for deeply embedded applications. The CM4 incorporates the same quad-core ARM Cortex-A72 processor, dual video output, gigabit Ethernet, UART, I2C, SPI, I2S, and a few PWM for good measure.
This module is available in multiple variants, with a range of RAM and eMMC Flash options, and with or without wireless connectivity. The modules are available with 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM with optional storage of 8GB, 16GB or 32GB eMMC Flash. The wireless option includes 2.4GHz and 5GHz 802.11b/g/n/ac wireless LAN and Bluetooth 5.0 for BT classic and BTLE support.
Note: We don’t include the Compute Module IO board, but it’s strongly recommended!
Compute ALL the THINGs!
Compared to the earlier Compute Module 3+, the CM4 features faster CPU cores, better multimedia, more interfacing capabilities, a range of RAM densities, and a wireless connectivity option. Instead of a DIMM socket, there are two board-to-board connectors that carry high-speed signals with ease - like multiple MIPI displays and camera ports. In addition to all the pins that supply Ethernet and SDIO and SPI and such, there’s also 28 GPIO pins, with up to 6 × UART, 6 × I2C and 5 × SPI.
On the video side, there are dual HDMI output, VideoCore VI graphics with OpenGL ES 3.x support, 4Kp60 hardware decode of H.265 (HEVC) video, and 1080p30 hardware encode of H.264 (AVC) video.

Compute Module 4 introduces a brand new form factor and a compatibility break with earlier Compute Modules. Where previous modules adopted the JEDEC DDR2 SODIMM mechanical standard, with I/O signals on an edge connector, we now bring I/O signals to two high-density perpendicular connectors (one for power and low-speed interfaces, and one for high-speed interfaces).
This significantly reduces the overall footprint of the module on its carrier board, letting you achieve smaller form factors for your products. This version is intended for experienced developers who will be using the board for industrial and commercial applications.

At first glance, the Pi Zero isn’t much. It just looks like a slimmed down version of the Raspberry Pi we know and love. But when we started to think of the possibilities - and what a well-chosen set of accessories could add - we realized the appeal. And then we saw the price…could it be true? Yes!
This is the slimmest, most pared down Raspberry Pi to date. It’s kind of like the little cousin to the Pi 2 - with just a micro SD card slot, a mini HDMI port, two micro USB ports (one for power, one for USB), and 512MB of RAM. It has a single-core 1 GHz processor chip, similar to the Pi A+ and B+.

MDBT50Q-DB demo board is designed for quick testing and debugging without building your own board. The board is only available with MDBT50Q-1MV2 (Chip Antenna) module.
Raytac nRF52840 module spectrum covers MDBT50Q-1MV2, MDBT50Q-P1MV2 and MDBT50Q-U1MV2 series with Chip Antenna, PCB Antenna and u.FL connector for External Antenna option for selection.
This USB dongle/key type thing is a little unusual - it isn’t a BLE adapter that you plug into a computer to add wireless capability. (If you do want something like that, our Bluetooth 4.0 USB Module will do the job nicely.) Instead, this is basically a minimal nRF52840 wireless microcontroller dev board on a stick. You can program it in Arduino or CircuitPython and it’s completely standalone. This could be useful for some situations where you want to have a standalone BLE device that communicates with a USB host but without dealing with the operating system’s BLE stack.
Each MDBT50Q-RX dongle comes pre-programmed with the TinyUF2 bootloader, which makes loading code onto it very easy (note that only the ones from Adafruit do this, its a special-order item). To enter the bootloader, hold down the dongle’s button while inserting into USB. The button can be used in Arduino/CircuitPython as an input. There’s also a single blue LED indicator. It’s all very simple but we could see situations where perhaps this acts as a beacon, a OS-less BLE interface or bridge, or a compact development board for experimenting with the nRF52840.
The blue LED is connected to P1.13, set that pin to be an output and pull low to turn on the LED
The button is connected to P0.15, set that pin to be an input with an internal pullup - when pressed the pin will go low.
Of course the best way to program these chips is with the Nordic SDK. This chip also has some basic Arduino support, CircuitPython support, and is supported by MyNewt.

A BB Q20 Keyboard in USB/PMOD/Qwiic format with a injection molded clear plastic case.
This is the evolution of our previous BBQ10 PMOD board. We took all the feedback from that board and improved on the design in every way.
We added a Qwiic/Stemma QT connector, we added USB HID support, we changed to a Q20 keyboard, which gave us four extra buttons, and the optical trackpad that works as a USB HID Mouse. And we decided to put the whole thing into a custom-designed injection molded clear plastic case for better usability and durability, as well as that retro 90s look.
The board uses the Raspberry Pi RP2040 MCU to poll the keyboard and trackpad and put the key press information into a FIFO.
You can use the I2C interface to read the FIFO, reconfigure the chip, and change the keyboar backlight.
In addition to that, the board also has a USB Type-C socket, and when connected to a desktop computer (Windows/Linux/MacOS), a smartphone (iOS/Android), or a SBC (Raspberry Pi, etc), it enumerates as a USB HID Keyboard and Mouse combo!
The firmware can be configured over USB using the Vendor Class interface.
The I2C interface is compatible with the old BBQ10 module, you can use the same libraries to interface this board.
Note: This board is not 5V-tolerant!
This board hasn’t been fully documented yet. Please make a pull request adding more info to this file.

The Cedar Grove StringCar M0 Express is an ATSAMD21-based CircuitPython compatible board used to control a simple string car racer robot. The board is architecturally similar to the Adafruit Trinket M0 and ItsyBitsy M0 Express microcontroller boards with the addition of battery management and a DC motor controller. This board features JST connectors for the racer’s battery, motor output, and sensor input. LiPo battery management charge rate is 500mA. For sensor experimentation, a 3.3-volt Stemma-QT connection is available on-board. The micro-USB connector used for REPL operation, operational status data output, and battery charging. On-board flash memory size is 2MB.
The StringCar M0 Express board will not be sold. The GitHub repository will contain all design files and links for the BOM and the shared OSH Park project.
The string car racer is a simple one-motor robot that is suspended from a string using a pulley attached to the motor shaft. Its challenge is to race back and forth from one end of a taut string to the other. The fastest car wins. The controller board uses sensor switches to detect the ends of the string, calculate the string length, then control motor speed and braking to avoid string-end collisions.
The objective is to create a string car racer that can autonomously learn about its environment and adjust tradeoffs for speed and battery longevity. CircuitPython is used to easily add and interactively adjust performance features such as motor and battery efficiency, end-of-string collision avoidance, string length calculation, and predictive braking. Also, being able to watch its own battery status means that it’ll always return to the home end of the string when battery capacity begins to wane. Circuit Python also supports libraries that abstract string car functions, simplifying the primary code module to make it easier for novice programmers to get involved in customizing string car racer operation.

It is especially useful for applications requiring large memory or a high degree of I/O expandability at an affordable cost, such as edge inferencing and remote monitoring.
Uniquely for Feather-compatible boards, Swan is designed to satisfy developers’ needs that span from early prototyping through high-volume deployment. Developers may begin to use Swan in conjunction with Adafruit’s myriad sensors and FeatherWing-compatible carriers. Due to its novel design, for high-volume deployment the low-cost Swan can also be soldered directly to a parent PCB integrating those sensors, utilizing the full range of Swan’s I/O capabilities.
The board has three independent power options – USB, Battery, or Line power – and provides a software-switchable 2 Amp regulator for powering external sensors. When operating in its low-power operating mode, the entire Swan board commonly draws only about 8uA while retaining all of its memory, making it quite suitable for battery-powered devices.
The Octave is a 12-key macropad. It is primarily designed to be a compact keyboard with support for 12 function keys (F1 - F12).
It is important that there are four rows. Just like the function keys on many keyboards are divided into four rows each. It is also important that it is easy to operate with one hand.
It is designed to be used with the left hand. In particular, the incremental encoder and stick controller are placed in easy-to-operate positions.
This board will allow you to clip in an ESP32-S2 WROOM or WROVER module for programming, prototyping and testing. Slot the module into the pins where it will be held securely while you upload your code.
The Board has two USB micro sockets: The first is connected to a CP2104 USB to UART to upload of your firmware and receive serial messages. The second is directly connected to GPIO19 & 20 that are the onboard USB - & + pins.
The board can be powered from either of the USB sockets, the UART USB has a power switch and the S2 USB will directly power the board. These sockets are separated by diodes so neither can reverse power the other. The S2 USB has bridgeable solder pads so that it can be used to supply USB power if acting as OTG Host.
The CP2104 handles the USB to UART conversion as well as putting the module into “programming mode”.
Where Espressif have enabled programming via the S2 USB and the module can be put in “programming mode” using the IO_0 and Reset buttons.

The Teensy 4.0 features an ARM Cortex-M7 processor at 600 MHz, with a NXP iMXRT1062 chip, the fastest microcontroller available today - ten times faster than the Teensy 3.2! The NXP iMXRT1062 is a ‘cross-over’ processor, which has the functionality of a microcontroller, at the speeds of a microcomputer. It’s perfect for when you need tons of flash, RAM and, to crunch lots of data, or when you need two full speed USB ports. It even has a graphics processor! All this for two sawbucks.
Teensy 4.0 can be programmed using the Arduino IDE with Teensyduino add-on.
Power Consumption & ManagementWhen running at 600 MHz, Teensy 4.0 consumes approximately 100 mA current, considerably more than most microcontrollers. To help reduce power, Teensy 4.0 provides support for dynamic clock scaling. Unlike traditional microcontrollers, where changing the clock speed causes wrong baud rates and other issues, Teensy 4.0 hardware and Teensyduino’s software support for Arduino timing functions are designed to allow dynamically speed changes. Serial baud rates, audio streaming sample rates, and Arduino functions like delay() and millis(), and Teensyduino’s extensions like IntervalTimer and elapsedMillis, continue to work properly while the CPU changes speed.
Teensy 4.0 also provides a power shut off feature. By connecting a pushbutton to the On/Off pin, the 3.3V power supply can be completely disabled by holding the button for 5 seconds, and turned back on by a brief button press. If a coin cell is connected to VBAT, Teensy 4.0’s RTC also continues to keep track of date & time while the power is off.
Teensy 4.0 also can also be overclocked, well beyond 600 MHz!
Technical Specifications
The Teensy 4.1, like the 4.0, also features an ARM Cortex-M7 processor at 600 MHz, with an NXP iMXRT1062 chip, the fastest microcontroller available today - ten times faster than the Teensy 3.2! The NXP iMXRT1062 is a ‘cross-over’ processor, which has the functionality of a microcontroller, at the speeds of a microcomputer. It’s perfect for when you need tons of flash, RAM and, to crunch lots of data, or when you need two full-speed USB ports.
Teensy 4.1 comes with four times larger flash memory than the 4.0, and two new locations to optionally add more memory. The Teensy 4.1 has the same form factor as the Teensy 3.6 (2.4” by 0.7”), but provides a ton more I/O capability, including an 100MB Ethernet PHY, SD card socket (SDIO connected), and USB host port. Please check out the Teensy 4.0 page for common specifications and features.
Memory
The bottom side of Teensy 4.1 has locations to solder 2 memory chips. The smaller location is meant for a PSRAM SOIC-8 chip. The larger location is intended for QSPI flash memory.
USB Host
Teensy 4.1’s USB Host port allows you to connect USB devices, like keyboards and MIDI musical instruments. A 5 pin header and a USB Host cable are needed to be able to plug in a USB device. You can also use one of these cables to connect to the USB pins.
Power Consumption & Management
When running at 600 MHz, the Teensy 4.1 consumes approximately 100mA current and provides support for dynamic clock scaling. Unlike traditional microcontrollers, where changing the clock speed causes wrong baud rates and other issues, Teensy 4.1 hardware and Teensyduino’s software support for Arduino timing functions are designed to allow dynamically speed changes.

The ARM Cortex-M7 brings many powerful CPU features to a true real-time microcontroller platform. The Cortex-M7 is a dual-issue superscaler processor, meaning the M7 can execute two instructions per clock cycle, at 600MHz! Of course, executing two simultaneously depends upon the compiler ordering instructions and registers. Initial benchmarks have shown C++ code compiled by Arduino tends to achieve two instructions about 40% to 50% of the time while performing numerically intensive work using integers and pointers. The Cortex-M7 is the first ARM microcontroller to use branch prediction. On M4, loops and other code which much branch take three clock cycles. With M7, after a loop has executed a few times, the branch prediction removes that overhead, allowing the branch instruction to run in only a single clock cycle.
Tightly Coupled Memory is a special feature which allows Cortex-M7 fast single cycle access to memory using a pair of 64 bit wide buses. The ITCM bus provides a 64 bit path to fetch instructions. The DTCM bus is actually a pair of 32 bit paths, allowing M7 to perform up to two separate memory accesses in the same cycle. These extremely high speed buses are separate from M7’s main AXI bus, which accesses other memory and peripherals. 512 of memory can be accessed as tightly coupled memory. Teensyduino automatically allocates your Arduino sketch code into ITCM and all non-malloc memory use to the fast DTCM, unless you add extra keywords to override the optimized default. Memory not accessed on the tightly coupled buses is optimized for DMA access by peripherals. Because the bulk of M7’s memory access is done on the two tightly coupled buses, powerful DMA-based peripherals have excellent access to the non-TCM memory for highly efficient I/O.
Teensy 4.1’s Cortex-M7 processor includes a floating point unit (FPU) which supports both 64 bit “double” and 32 bit “float”. With M4’s FPU on Teensy 3.5 & 3.6, and also Atmel SAMD51 chips, only 32 bit float is hardware accelerated. Any use of double, double functions like log(), sin(), cos() means slow software implemented math. Teensy 4.1 executes all of these with FPU hardware.

A kick-ass microcontroller board with everything you need in a compact package that fits in your pocket. Integrated battery, power management system, Arm microcontroller, USB bootloader, 4 high-power PWM outputs, and 12 GPIOs.
Why? After years of wiring together portable LED controllers that all consisted of a lithum batter, charge controller, power switch, and an arduino nano (or similar), I wanted something better. I always found those versions to be janky and fragile – not to mention concerned that damaging the pouch cell battery might make it explode! This board has everything I need with room to expand.

The ScoutMakes Azul is an open source Bluetooth (BLE) development platform featuring the nRF52840 (32bit ARM Cortex-M4 processor) from Nordic semiconductors enabling excellent Bluetooth development capabilities for your project. It conforms to the Adafruit feather format, runs CircuitPython, Arduino. The platform also has native USB support.
To enable even more integration, a 128x32 OLED is also built in along with USB-C support and a power switch for ease of use.
The platform come pre-programmed with a UF2 bootloader and CircuitPython ready to go out of box. You can pair the Azul with Adafruit bluefruit application in iOS or Android to get going. The application includes a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad. This data can be read over BLE and processed directly by the nRF52 microcontroller.
Thumby is the tiniest handheld console - play games at the tips of your thumbs, give yourself a cool keychain accessory, and easily learn to code with this all-in-one piece of tech! This miniature console features a responsive D-pad and two action buttons, offering a fully playable experience.
When you’re not going for the high score or creating your own games, the super-small system dangles from your keys as a tiny totem of nostalgic gaming. Thumby proves that great things really do come in small packages.
Thumby Color is the next generation of Thumby; it’s still fun to play with, easily programmable, and as tiny as ever.
Built around the new Raspberry Pi RP2350 Processor, the successor to the RP2040 used in the original Thumby, the Thumby Color is significantly more powerful than the original Thumby. This new powerful processor enables us to implement a vibrant color screen and a highly featured game engine, allowing for the creation of some amazing games!
The NeoTrellis M4 is an all-in-one USB + NeoPixel + Elastomer + Audio board. It’s powered by the SAMD51, a Cortex M4 core running at 120 MHz. This chip has a speedy core with CircuitPython support, hardware DSP/floating point, dual DACs and all the goodies you expect from normal chips like I2C, ADC, DMA, etc. It has a roomy 512KB of flash and 192KB of SRAM so it’s great for CircuitPython, includes a full 8MB flash chip so tons of space for files and audio clips.
The native USB port can turn it into a MIDI USB device if you like - currently that’s only supported in Arduino. Tether it to a computer or tablet, if you like. Or use it in standalone mode, as long as its powered from a USB power plug, it’ll run whatever firmware is burned into it.
OK so you’ve got this big brain, but now you need inputs and outputs! There’s a 4x8 grid of elastomer button pads with a NeoPixel nestled in the center of each one. You can read any/all button presses simultaneously thanks to the fully diode’d matrix, and also set each button color to any of 24-bit colors. The elastomer buttons are translucent so they glow beautifully when lit.
Time to make some noise! Adafruit picked the SAMD51 mostly because it has dual DACs - that’s two 12-bit, 500KSPS ‘true analog’ outputs connected them to left and right on a standard headphone jack. Since the DAC pins are also ADC pins you could also use the left/right for audio line level input if you so choose. You’re not going to get audiophile-quality outputs from two 12-bit DACs but you can certainly play audio clips and make beeps and bloops.
To add more interactivity, a precision triple-axis accelerometer from Analog Devices, the ADXL343, is included as well, and provides sensor information on tilt, motion, or tapping. Great for adding another dimension of data input in addition to the button pads.
Finally, a 4 pin JST hacking port is available for extra add-ons. It’s STEMMA and Grove compatible, and provides GND, 3.3V power, and two pins that can be used for I2C, ADC, or a UART. So connect some other sensor, or read stereo audio in, or maybe hack together a MIDI port. Whatever you like!

The Adafruit Trinket M0 may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATSAMD21, a little chip with a lot of power. Adafruit designed a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s one of the lowest-cost CircuitPython programmable boards!
Adafruit used the same form factor for the original ATtiny85-based Trinket and gave it an upgrade. The Trinket M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 powerhouse. It’s just as small, and it’s easier to use, so you can do more.
The most exciting part of the Trinket M0 is that while you can use it with the Arduino IDE, it ships with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with code.py on it. Edit code.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can’t install software on. When you’re done, unplug the Trinket M0 and your code will go with you. Please check out the Trinket M0 CircuitPython guide for a list of capabilities and quick-start code examples - CircuitPython is easier to code but not as low-level and complete as Arduino.
Here are some of the updates you can look forward to when using Trinket M0:
Each is fully assembled and tested Trinket M0 with CircuitPython & example code programmed in.
So what are you waiting for? Pick up a Trinket M0 today and be amazed at how easy and fast it is to get started with Trinket and CircuitPython!
This is a Trinket M0 that has been had a SPI flashchip bodged on by Dave Astels. It is not available for purchase.

Yet powerful!
Despite a size smaller than the ATMEGA328 which powers Arduino Uno, uChip mounts the same ATSAMD21 series of Arduino Zero! Everything that runs on Arduino Zero runs also on uChip, at the same speed! However, unlike Arduino Zero, it fits a 16-pin DIP socket and it leaves a lot of space on your breadboard. No more bulky shields or flying wires all around your breadboard!
And now uChip runs CircuitPython too!
Unlike many Arduino Zero compatible board, uChip also mounts a high efficiency buck converter, which converts the USB voltage down to 3.3V at up to 1A, which is provided on pin 16, for the external circuitry. A software-selected pass-through mode also allows to output 5V instead of 3.3V.uChip can operate also as an USB host. For this purpose, a built-in boost converter can provide up to 500mA to the external USB device, even when the input voltage is as low as 3.3V. The built-in automatic power-path management prevents external power from being fed into an USB port, when uChip is connected to a PC/Mac, and a voltage is provided also externally on pin 16.
You can program uChip using virtually any IDE, in many languages (CircuitPython too!) and you can choose of using either the USB port or an external SWD programmer.

All sources are open, including:
For peripherals, there are two I2C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO - check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).
You’ll note there’s no I2S peripheral, or SDIO, or camera, what’s up with that? Well instead of having specific hardware support for serial-data-like peripherals like these, the RP2040 comes with the PIO state machine system which is a unique and powerful way to create custom hardware logic and data processing blocks that run on their own without taking up a CPU. For example, NeoPixels - often we bitbang the timing-specific protocol for these LEDs. For the RP2040, we instead use a PIO object that reads in the data buffer and clocks out the right bitstream with perfect accuracy. Same with I2S audio in or out, LED matrix displays, 8-bit or SPI based TFTs, even VGA! In MicroPython and CircuitPython you can create PIO control commands to script the peripheral and load it in at runtime. There are 2 PIO peripherals with 4 state machines each.
There is great C/C++ support, unofficial (but really good) Arduino support an official MicroPython port, and a CircuitPython port! We of course recommend CircuitPython because we think its the easiest way to get started and it has support with most our drivers, displays, sensors, and more, supported out of the box so you can follow along with our CircuitPython projects and tutorials.
While the RP2040 has lots of onboard RAM (264KB), it does not have built in FLASH memory. Instead that is provided by the external QSPI flash chip. On this board there is 2MB, which is shared between the program its running and any file storage used by MicroPython or CircuitPython. When using C/C++ you get the whole flash memory, if using Python you will have about 1 MB remaining for code, files, images, fonts, etc.
RP2040 Chip features:

Flexible I/O connects RP2040 to the physical world by allowing it to speak to almost anyexternal device. High performance breezes through integer workloads. Low cost helps ease the barrier to entry.
This isn’t just apowerful chip: it’s designed to help you bring every last drop of that power to bear. With six independent banks of RAM, and a fully connected switch at the heart of its bus fabric, you can easily arrange for the cores and DMA engines to run in parallel without contention.

Technical details
Tiny, but mighty! This board with a powerful ESP32-S3 MCU measures in at 24.8mmx18mm (23.5mm for just the PCB, the USB-C connector sticks out a little bit). Despite it’s small size it still exposes a wealth of GPIO connections - a whopping 34 in total. It does however have ‘only’ 4MB of Flash storage rather than the more typical 8MB found on most ESP32-S3 boards (and even 16MB on some).
Due to the limited flash memory available on this board it hasn’t been ‘build’ with esp-camera support - if that’s something you want to use you’ll have to roll your own build and sacrifice some other feature to make space (like the at the moment non-functional bluetooth)

The WEMOS LOLIN32 Lite Board is the successor to the ESP8266. In addition to WiFi, the microcontroller also has Bluetooth and Bluetooth LE as well as more IO pins and improved analog inputs. The ESP32 can be programmed under Arduino. However, the board needs to be integrated first. I recommend the ESP32 only for advanced users, as it is not yet supported by all Arduino libraries. In addition to the WiFi/BLE SoC, the Lolin32 board includes a CH340G that converts USB to serial and allows your computer to communicate with the microcontroller. The LOLIN32 also has a LiPo charger with connection for 3.6V LiPo’s, so you can realize your ESP32 project battery-powered and really wireless.
The ESP32 is great for small projects where you don’t need so many I/Os, processing power or interfaces.
