PCB adapter for Raspberry Pi to Hub75 RGB Matrixes

Since hand-wiring can be a little tedious, here are some PCBs that help with the wiring when using the rpi-rgb-led-matrix code.

Passive is the simplest one, directly wiring the GPIO pins to the Hub75 IDC connectors for up to two parallel chains (for 40 GPIO pin Raspberry Pis. Older 26 GPIO pin Raspberry Pis can connect to one chain).
Active Similar to the passive PCB, but does level shifting 3.3V -> 5V and provides convenient breakouts for I²C and serial.
Active3 Like the active board, but supports three parallel chains with level shifting. Due to the additional amount of GPIO pins needed, I²C and serial can't be used when all three ports are used. (Buy the boards from OSH Park).
