As a bit of an experiment, I thought I'd try loading CircuitPython for the Raspberry Pi Pico onto my Neotron Pico board. Whilst the point of the board is to develop and run the Neotron OS, I found that Circuit Python was pretty useful for developing PCB tests and checking out various bits of functionality. The main advantage was that I could interact with well-tested libraries and not have to wonder if my code was wrong or the PCB was wrong!
