CircuitPython

CircuitPython (https://adafru.it/tB7) is a derivative of MicroPython (https://adafru.it/BeZ) 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.

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 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!

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 Metro M0 Express might already come with CircuitPython but maybe there's a new version, or you

loaded your Metro M0 Express with Arduino code! In that case, see the below for how to reinstall or update

CircuitPython. Otherwise you can skip this and go straight to the next page.
