*Description of the second function pin

When the self-design of the CAN transceiver circuit or the improvement of the CAN signal line protection level is required, the TTL signal on the second function pin of CAN signal may be introduced into the base plate through the MiniPCIe reserved pin. The self-design of CAN transceiver circuit has improved system flexibility.



The second function pin of CAN signal is switched through R24. R24 is welded by default. The system uses the default on-board CAN isolation transceiver. In case R24 is eliminated, the second function pin of CAN signal will automatically start when the system is powered on.
