LED Cube driver
Version 2 - Last update: Oct 5, 2015

Driver board for a 4x4 RGB LED matrix - 4 together will drive a cube. It's not the most efficient design (4 arduinos for a cube is excessive) but it's a prototype that will be scaled up to a 12 x 12 x 12 later. The two outer pins on either side are the common return for the four rows, the other pins are for the R,G and B in each column. It's designed to be controlled over the I2C bus since those are the only spare pins left. 5 pin connector pinout is:

1 - Reset

2 - Vcc

3 - Ground

4 - I2C

5 - I2C
