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!
Follow this quick step-by-step for super-fast Python power :)
If double-clicking doesn't work the first time, try again. Sometimes it can take a few tries to get the rhythm right!

Trinket M0 is limited on space. As you begin working on projects, you may run out of space. Operating systems can create hidden files that take up space. To prevent these files from being added to your Trinket, we suggest installing the Trinket Default Zip.
