60% Gherkin
Two Gherkin PCB's mounted to a double base plate. The two 5x6 matrices combined into a single 10x6 matrix.Both PCB's are connected to a single Pro Micro. One switch from each column is bridged to the corresponding switch on the other PCB. The header is used to bridge the connections for the unused pins, VCC and ground to the other PCB. Where the other Pro Micro would have been the unused pins are jumpered to the correct rows.
The backlight also works. A single MOSFET is used to control all the LEDs on both PCBs.
Details of the pinout and modified firmware can be found on Git.
