RGB Matrix V3.03 - fully assembled

The new V3.03 boards now support auto reset (and disabling it with a jumper) and use 74HC595 instead of 74HCT595. This adds some brightness to the matrix and gives much better white light reproduction. Also I've fixed a minor pin offset in the LED matrix connectors. The silkscreen was also updated and now shows the correct outline of the LED matrix. Pin-1 markers for all relevant components have been enhanced as well.
