Internal IO A and Internal IO B Connectors

The Internal IO A and Internal IO B connectors are PHS26MRS – robust 26-pins straight shrouded 0.1" pitch flat cable headers. They provide the connections for the two sets of 10 I/O ports, 5V, and 12V power outputs.

26-pin male receptacle, dual-row 2.54mm pitch, straight shrouded header
