If you'd rather use CircuitPython that's really easy too - scroll down to the bottom of the tutorial for a quick primer on how to get things started. Like all our RP2040 boards, you can use it with C++, MicroPython or CircuitPython - we'll be using our custom build of MicroPython in this tutorial. We've designed it to be compact, easy to use and straightforward to power. Plasma 2040 is an LED strip driver board that uses the shiny new RP2040 chip from Raspberry Pi.
