Now we'll set up the CPX for CircuitPython mode to be able to upload the code we write to the board.

If your CPX is already in CircuitPython mode, double check it is updated  the latest version. You will know you are in CircuitPython mode if the drive CIRCUITPY shows up on your computer when connected via micro usb cable to your computer.

If this is your first time using your CPX with CircuitPython or you see a drive entitled CPLAYBOOT, follow the steps and extended guide below to switch to CircuitPython mode.

  • First install or update CircuitPython. This will give you a .uf2 file.
  • Next, plug the CPX into a computer via micro usb cable and double click the reset button (NeoPixels should turn green).
  • Now drag the recently downloaded .uf2 file onto the CPLAYBOOT drive.
  • The drive should disappear and come back as CIRCUITPY.

Here is an extended guide on how to follow the above steps with images and pictures to help.

If issues are still arising while getting into CircuitPython mode, check out this troubleshooting guide.
