Maker Feather AIoT S3
by Cytron Technologies
The Maker Feather AIoT S3 is powered by the ESP32-S3 WROOM 1 N8R8 module with 8MB Flash and 8MB PSRAM. This board allows the users to access both AI and IoT applications on their own projects. Users may choose from two different variants of Maker Feather AIoT S3: Basic (without pre-soldered female headers) and Pre-soldered female headers which the user can use a breadboard to expand all the GPIOs.
The board comes with 3 Maker Ports (STEMMA QT / Qwiic JST SH) that have flexible I/O options: digital, analog and I2C. The Maker Ports consist of 2 horizontal ports that are powered by VPeripheral that allows users to save power by turning on and off via programming code and 1 vertical port that is powered by constant 3.3V.
There are 11 LEDs that act as the status LED of their respective GPIOs, a programmable Neopixel RGB LED to make your project colourful, 1 “RESET” and 1 “BOOT” buttons to reset the board and enter bootloader mode and a programmable push button. At the bottom of the board, there is a piezo buzzer with a mute switch that allows you to add audio features to your projects.
There are 2 ways to power up the Maker Feather AIoT S3, either through USB C Data Cable or rechargeable LiPo/Li-Ion Battery. The built-in 1-cell LiPo/Li-Ion charger port comes with overcharged and over-discharged protection features.
This board is pre-loaded with CircuitPython and is also supported by various programming languages: MicroPython, Arduino IDE and Espressif IDF.

Absolute Newest
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. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
Install, Repair, or Update UF2 Bootloader
Latest version: 0.20.1
The UF2 bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader is not CircuitPython. If a UF2 bootloader is installed, you can check its version by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FTHRS2BOOT, MAGTAGBOOT, HOUSEBOOT, etc.)
It is not necessary to reinstall a UF2 bootloader you unless a BOOT drive is not visible when in UF2 bootloader mode, or you know of a problem with your current UF2 bootloader.
If a UF2 bootloader has never been installed on the board, or the UF2 bootloader was removed by erasing or overwriting the flash, the UF2 bootloader must be installed in order to flash .uf2 files onto the board. .bin files can be uploaded without a UF2 bootloader, using the ESP Web Flasher or esptool.py.
Note: update.uf2 files are not currently working on ESP32-S2 or ESP32-S3 boards.
Important: this will erase previously flashed firmware and sketches from the board, but needs to be perfomed only once.
The instructions here are general. We recommend you consult the manufacturer's board documentation for detailed instructions, which may be different.
- Unzip to find the file combined.bin.
- Place board in bootloader mode:
- Plug board into a USB port on your computer using a data/sync cable. Make sure it is the only board plugged in, and that a charge-only cable is not being used.
- Press and hold down the BOOT or 0 button.
- Press and release the RESET or RST button.
- Release the BOOT button.
- Upload combined.bin (Google Chrome 89 or newer):
- Open ESP Web Flasher in a new window/tab.
- Select 460800 Baud from the pull-down menu (top-right).
- Click Connect (top-right).
- Select the COM or Serial port from the pop-up window.
- After successful connection, click Erase.
- After successful erase, click any Choose a file..., then locate and select the combined.bin file unzipped earlier.
- After successfully choosing combined.bin, click Program.
- After the TinyUF2 firmware update is complete, press the RESET button on the board. A new drive BOOT should be visible in your file browser.
After installing the UF2 bootloader, enter the bootloader by double-clicking the reset button. On boards with an RGB status LED, tap reset once, wait for the LED to turn purple, and tap again before the purple goes away. On other boards, consult the board documentation.
After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to load or reload CircuitPython using the .uf2 file.
