by Solder Party
The Stamp was created to allow you to use the Raspberry Pi RP2040 in your designs without having to solder small-pitch QFN chips or worry about lots of external circuitry.
All you need to get you started is a 5V supply or a LiPo battery. The Stamp will take care of the charging and switching the power sources.
The castellated edges with 2mm pitch can be hand-soldered directly to a carrier board or by using pin headers. You can find footprints for many PCB programs here.
At only 1 by 1 inch, the Stamp packs a lot of features:
- 8MB of FLASH
- 500mA 3.3V LDO
- All 30 GPIOs broken out
- A Neopixel
- LiPo supply and charging circuit (with charging LED)
- USB broken out
- SWD broken out
- Reset Button
- 12MHz crystal
and of course, everything that comes with the Raspberry Pi RP2040 itself:
- Dual core ARM Cortex-M0+ @ 133MHz
- 264kB SRAM
- 2 UARTs
- 2 SPIs
- 2 I2Cs
- 16 PWM channels
- USB with Host and Device support
The RP2040 comes with a pre-programmed ROM UF2 Bootloader, by pulling the BOOTSEL pin low and resetting, or by double-pressing the RESET button (if the FW supports it), you can upload new firmware using the USB disk drive.
In addition to the Stamp, we also offer a reference design - the RP2040 Stamp Carrier.
The CircuitPython firmware for the Stamp comes with a built-in board file for the Carrier, you can access it using
import stamp_carrier_board as board. After that, you can access all the Carrier pins and interfaces like you would with any other CPY board.

This is the latest unstable release of CircuitPython that will work with the RP2040 Stamp.
Unstable builds have the latest features but are more likely to have critical bugs.
Built-in modules available: _bleio, adafruit_bus_device, adafruit_pixelbuf, aesio, alarm, analogio, atexit, audiobusio, audiocore, audiomixer, audiomp3, audiopwmio, binascii, bitbangio, bitmaptools, bitops, board, busio, countio, digitalio, displayio, errno, fontio, framebufferio, getpass, gifio, imagecapture, json, keypad, math, microcontroller, msgpack, neopixel_write, nvm, onewireio, os, paralleldisplay, pulseio, pwmio, qrio, rainbowio, random, re, rgbmatrix, rotaryio, rtc, sdcardio, sharpdisplay, storage, struct, supervisor, synthio, terminalio, time, touchio, traceback, ulab, usb_cdc, usb_hid, usb_midi, vectorio, watchdog
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
