V1 Hub75 driver board.
Order from OSH Park: https://oshpark.com/shared_projects/DTnHhcQ1 Firmware: https://github.com/joe714/pixelclient
The USB port on this board is for power only for cost reasons. You will need a USB to TTL serial adapter connected to J2 to do the initial firmware load.
J3 is the data connector for the HUB 75 panel. There isn't enough clearance to use a keyed shrouded header,
