Main Supply and I/O Header (J3)

All key I/O and supply GND functions are brought to this header. This header can be used on either interface to test equipment or a short cable can be made to connect to an existing customer-application board with a CAN controller.

This header is arranged to provide a separate ground for each signal pair (TXD/GND and RXD/GND). If the EVM is being used with lab equipment, connect separate cables to these main points via simple 2-pin header connectors. If connecting the board to a processor-based system, connect a single cable with all power and signals via a 12-pin header cable to this port.
