The controller board is a circuit board that plugs right into your Raspberry Pi (aka Raspberry Pi HAT). It contains an Arduino Nano that is used to correctly time the signal required to control the WX Map LEDs.
It also contains:
- A 2 pin input header (2.54mm) that provides power to the Pi and Nano
- A 3 pin output header (2.54mm) that provides power, and signal to the LEDs
