More information in blog:

http://www.40percent.club/search/label/gnap Scroll down and read the older posts first.

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
