RGB Matrix V3.04 - back
Slightly updated PCB. Now the boards are blue, the pads are gold plated, only 1mm thick and the silkscreen has been revised and now shows Arduino pin functions for PORTC and PORTD.
This batch of 25 boards was made by MakePCB.com - very affordable but also quite slow. My first order took about 5 weeks. GoldPhoenix just took about 1 week, but at a higher price.
