8x8 Matrix drive PCB

Current project LED Matrix and drive PCB

Using an Arduino write code to drive a 8x8 matrix of 20ma LEDs with column drive by source driver M54564P and row drive using serial to parallel convertor stpic6d595. The drive PCB can be used to drive any matrix or 8 segment display, although this PCB is for 5V drive a simple modification will allow upto 20V and 150ma.
