Adafruit Circuit Playground Express Cheatsheet

This is a cheatsheet for getting up and going with the Adafruit Circuit Playground Express using CircuitPython.

Setup

How can I work out what version of Circuit Python I'm using?

When you plug the device into a USB port it should mount a drive called CircuitPy. In the root of this drive should reside a file called boot_out.txt. This will contain version information for the device, e.g.
