+# 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
