NOT an official Framework module. Just reference firmware that's easy to get started with, without having a Framework module. Has GPIO and WS2812/Neopixel compatible RGB LED.
When booting up this LED is lit in green color. Its color and brightness can be controlled via the commands:
> ./ledmatrix_control.py --brightness 255
> ./ledmatrix_control.py --get-brightness
Current brightness: 255
> ./ledmatrix_control.py --set-color yellow
> ./ledmatrix_control.py --get-color
Current color: RGB:(255, 255, 0)
