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. Simply copy and edit files on the CIRCUITPY drive to iterate.

The following instructions will show you how to install CircuitPython. If you've already installed CircuitPython but are looking to update it or reinstall it, the same steps work for that as well!

CircuitPython Quick Start!

Follow this quick step-by-step for super-fast Python power :)

Click the link above to download the latest UF2 file.


Download and save it to your desktop (or wherever is handy).

Plug your BLM kit into your computer using a known-good USB cable.

A lot of people end up using charge-only USB cables and it is very frustrating! So make sure you have a USB cable you know is good for data sync.

Double-click the Reset button on the top in the center of your board, and you will see the NeoPixel RGB LEDs around the edge of the board turn green. If they turn red, check the USB cable, try another USB port, etc. Note: The little red LED towards the top of your board will pulse red. That's ok!

If double-clicking doesn't work the first time, try again. Sometimes it can take a few tries to get the rhythm right!

You will see a new disk drive appear called BADGEBOOT.




Drag the adafruit_circuitpython_etc.uf2 file to BADGEBOOT.

The LEDs will flash. Then, the BADGEBOOT drive will disappear and a new disk drive called CIRCUITPY will appear.


That's it, you're done! :)
