56-Pin I/O Connector

All of the ooPIC's electrical connections are available at the 40-pin expansion connector.
It provides the following connections.

16 Digital I/O lines
Power (regulated, unregulated & optional)
4 Analog-to-digital converters

The connector is a 40-pin, .100 inch spacing, connector commonly used on IDE hard drives with 4 sets of 4-pin .100 inch spacing, connectors beside it.

The following table shows the pin assignments for the 56-pin I/O Connector:
