This PCB is used to hold an Arduino Nano and to connect a Neo-Ring, 6 individual Switches with built in LED's and a Bluetooth module. It now also has two spare pins at the end for Steering Wheel position sensors

This is still in progress but you will connect 6 push button momentary switches with a ground feed. The arudino pins have pullups enabled and the NPN/PNP transistor array switches on power to the LED's in the switches when the vehicle lights are on.
