Dusty-to-M7 Interface
This section describes the physical I/F between the Dusty module and the M7 space
on the DuinoPro.
The Pin Name and Pin No. in the following tables refer to the references
used in the module (see UNO DuinoPro Schematic).
Net refers to anything immediately connected to those pins (N/C indicates no connection).
