2.2 Board description
The WCT board is connected to the system by the main power connector. It comprises the automotive
battery connection (red wire = +12 V line, black wire = GND line), the CAN connection (yellow wires),
and the IGNITION (blue wire).
The connectors on the bottom edge of the board provide a JTAG connection for programming and
debugging, 2xSCI for the FreeMASTER tool connection for the debug option and the console connection,
and the temperature connector and backup touch sense connector are placed on the edge of the board. The
thermal resistor circuits can be used to develop the temperature sensing and protection.
The circuitry on the board is covered by the metal shield to lower the EMI and provides a fixed position for
the coils.
