********************* 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).
