The Adafruit Trinket M0 is a powerful, yet tiny, microcontroller based on the Atmel ATSAMD21 chipset. The board is small enough to fit in any product and priced low enough to use without worry. Best of all, the Trinket M0 supports Circuit Python!

This is Adafruit’s lowest cost CircuitPython board – these are shipped with CircuitPython pre-installed and ready to roll. Simply plug it in to your computer using a micro-USB cable and it will appear as a very small disk drive. Edit the main.py file with any text editor to create your code and use it in your project. There is no IDE or compiler required, so it can work with just about anything that can see a flash drive and edit a text file.

If you prefer working with Arduino, the Adafruit Trinket M0 is also Arduino IDE compatible – to set it up for Arduino, just check out the Getting Started Guide listed in the resources below!

On the hardware side, this board is very capable. The Trinket M0 can be used in Arduino or CircuitPython as USB serial console, Keyboard/Mouse HID, even a little disk drive for storing Python scripts.
