CircuitPython is a programming language designed to simplify experimenting and learning to code on low-cost microcontroller boards. With CircuitPython, there are no upfront desktop downloads needed.

These versatile chips take the bother of scanning the LED matrix away from the microcontroller with their own internal frame registers fed from an I2C interface.

There are lots of examples around if you want to get started, and we’re maintaining our own list of CircuitPython projects over on hackaday.io that you can check out. You can see a video of the ...
