Pro Micro splittest

To trigger keypress, short together pins B3 and B6 (marked on the PCB as 14 and 10).

Wiring

  • Add switches to both Pro Micros across B3 and B6 pins
  • Add pull-up resistor to left side between VCC and F6
  • Add pull-down resistors to right side between GND and F6
  • Connect the following pins on both sides together: D0, D1, GND, VCC
  • Add I2C 4.7kOhm resistors between D0 and VCC, and D1 and VCC
  • Wire Di of RGB strip for each half to D3
