3.7CAN0 – CAN2

Three high-speed CAN-transceivers (PCA82C250) are on-board to connect all available on- chip CAN to 9-pin D-Sub connectors (X9, X10 and X11).

JP82 Connects MCU RX0 to CAN transceiver U15 JP83 Connects MCU TX0 to CAN transceiver U15 JP87 Connects MCU RX1 to CAN transceiver U18 JP88 Connects MCU TX1 to CAN transceiver U18 JP89 Connects MCU RX2 to CAN transceiver U19 JP90 Connects MCU TX2 to CAN transceiver U19

3.8LIN / RS-232 UART

There are three UART connectors X1, X4 and X8 (9-pin D-Sub) on-board, which can be used for RS-232 or LIN communication (to get information in detail about pin usage, please refer to chapter 4.2 UART / LIN Connector (X1, X4, X8)). The LIN transceiver needs to be configured as LIN-master or LIN-slave.
