Digital IO Board

The Digital IO board radically changes how IO is handled in the SPECTRE autopilot. Previously each IO line was connected to the processor, but this restricted the number of IO lines available. The Digital IO board has been integrated into the Mk 4 SPECTRE. Each board has 8 digital inputs, optically isolated, and 8 relay outputs which can handle high current. These boards are added to the SPECTRE motherboard, and multiple boards can be used on a single bus.

Each output is rated at 2A at 30VDC.
