Notes
- The PCB is a single reversible board, flip it over for the right side
- The Pro Micros need to be attached upside down on the left and right side up on the right for the correct pin alignments
- Currently the QMK firmware has the side hardcoded and needs to be complied individually for each side. To switch between compiling the left/right side firmware, uncomment the appropriate line in the config.h (Lines 16/17)
- There are free pins (D2, D3) that could be used for high/low indication of side
