* Description of pin switching of the second function

When you need to design the CAN transceiver circuit or improve the protection level of the CAN signal line, you can connect the TTL signal of the second function pin of CAN signal to the base plane through the Mini PCIe reserved pin, and design the CAN transceiver circuit to improve the flexibility of the system.

The second function pin of CAN signal is switched through R24. R24 is soldered by default, and the system adopts the default onboard CAN isolation transceiver. When R24 is removed, the second function pin of CAN signal is enabled automatically when the system is powered on.
