CircuitPython

CircuitPython is a derivative of MicroPython designed to simplify experimentation and education on low-cost

microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads.

The trinket M0 is the second board that comes pre-loaded with CircuitPython. Simply copy and edit files on the

CIRCUITPY drive to iterate.

If you've already plugged your board into your computer, you should see a drive called CIRCUITPY. The drive will

contain a few files. If you want to make a 'backup' of the current firmware on the device, drag-off and save the

CURRENT.UF2 file. Other that that you can ignore the index.htm and info_uf2.txt files. They cannot be deleted and are

only for informational purposes.

If you have already plugged in your board, start by ejecting or "safely remove" the CIRCUITPY drive. This is a good

practice to get into. Always eject before unplugging or resetting your board!

Download and save it to your desktop (or wherever is

handy).

As we continue to develop CircuitPython and create new releases, we will stop supporting older releases. If

you are running CircuitPython 2.x, you need to update to 3.x: https://learn.adafruit.com/welcome-to-

Your Trinket M0 already comes with CircuitPython but maybe there's a new version, or you overwrote your

Trinket M0 with Arduino code! In that case, see the below for how to reinstall or update CircuitPython.
