ISO 11898 defines the CAN bus physical layer. CAN_H is 3.5V dominant and CAN_L is 1.5V. Requires 120-ohm termination resistors at each end of the bus.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | CAN_H | CAN bus high 3.5V dominant | BUS |
| 2 | CAN_L | CAN bus low 1.5V dominant | BUS |
| 3 | GND | Shield signal ground | GND |
