i-MOD CAN

The i-MOD CAN connector is a standard connector defined by Keith & Koep to allow customers to easily add a CAN transceiver & connector to the baseboard.

This is the pinning of the connector on the baseboard.
Extension boards use the opposite numbering scheme.

Pin Signal Function
1 +5V Power
2 CAN_GPIO2 Generic GPIO
3 CAN_GPIO3 Generic GPIO
4 GND Power
5 +3V3 Power
6 CAN2_TX Single ended TX output of CAN port 2
7 CAN2_RX Single ended RX input of CAN port 2
8 CAN1_TX Single ended TX output of CAN port 1
9 CAN1_RX Single ended RX input of CAN port 1
10 CAN_GPIO0 Generic GPIO

Connector: 687110149022 by Wuerth

The CAN_TX and CAN_RX are single-ended 3V3-level signals. A CAN-transceiver is needed to convert these to a differential CAN signal.

CAN_GPIO signals may be used for auxiliary functions, i.e. enabling CAN-termination.
