Contoller Area Network (CAN)

The gd32f303 mcu has an onboard CAN controller connected to an unknown external CAN transceiver (x217A)

Whilst CANL and CANH typically have a 120 Ohm as terminating - the resistance measured between CANH andCANL is 240 ohm, suggesting that 4 cybergears might be expected on the bus to result in required 60 ohm.
