i-MOD CAN - i-MOD standard
The i-MOD CAN connector is a standard connector defined by Seco to allow customers to easily add a CAN transceiver & connector to the baseboard.
This is the pinning of the connector on the carrier board.
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 |

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.
iMod CAN peripherals
Picture | Name | Description | Datasheet |
|---|---|---|---|
iModCon CAN non-isolated | Board with one non-isolated CAN-transceiver. The CAN2-pins are routed to a second iMod CAN connector, so that two iModCon CAN boards can be attached to a single iMod CAN interface. |
