BOM for PCB

    1	Pro Micro (5v, 16MHz)
    2	12pin SIP headers or a 24 pin socket
    47	1n4148 diodes
    47	switches
    1	mini USB connector Molex part 54819-0519
    1	cut up micro USB cable


Needed in addition if you want LEDs

    1	Pro Micro  (5v, 16MHz)
    2	12pin SIP headers or a 24 pin socket
    47	LEDs, Use the brightest possible, LEDs will be on only 1/12th the time at full brightness due to matrix scanning.
    4	Resistors for LEDs. Use online LED caculator to choose value. Target 10ma output.

Needed for GNAP 2.0

    1	Cherry PCB mount 2U stabilizer
