Unexpected Maker ESP32-S3 boards can be used with CircuitPython, MicroPython, ESP-IDF or Arduino.
Your board ships with the latest version of CircuitPython with ESP32-S3 support.
It also ships with the UF2 bootloader, so you can easily update your board with the latest CircuitPython firmware, whenever you desire.
Just plug your board into your computer and it will appear in your filesystem as a USB flash drive! Just copy your code over, or edit your code directly on the drive. Coding a microcontroller has never been easier!
As newer versions of CircuitPython are released, you are able to update as you require from circuitpython.org
If you need to grab the shipping CircuitPython code that comes with your board, you can grab the latest here
MicroPython has excellent support for the ESP32, and that includes the ESP32-S3.
If you would like to put MicroPython on your new board, please follow the flashing guide for your board from this firmware link and don't forget to erase your flash first!
For more information about developing projects on your new board, using MicroPython, check out the MicroPython documentation.
ESP32-S3 support in the IDF is part of the v4.4 release. The latest IDF is v5.0, but it's in early development, so I recommend you stick to the v4.4 release branch for the time being as there are some low level breaking changes in v5.
Check out the ESP32-S3 IDF docs for information on how to install it and develop for the ESP32-S3
If you have not already setup your Arduino IDE environment to work with ESP32, please follow the official Espressif ESP32 Arduino Core instructions to install it.
Arduino support for the ESP32-S3 is available in 2.0.3 and later. Please install the latest version to be able to select ESP32-S3 boards with the latest fixes and features.
The Unexpected Maker ESP32-S3 github Repo includes the following items:
- 3D STEP file for the TinyS3
- KiCAD 6 symbol file for the TinyS3 that you can use when integrating one of them into one of your PCB designs
- KiCAD 6 footprint file for the TinyS3
- PDF Schematic for the TinyS3
- Hi-res pinout reference card for the TinyS3
- Fritzing parts (soon)
