CAN

Jetson Orin NX brings a single controlled area network (CAN) interface to the main connector.

Pin # Name Orin Signal
143 CAN_RX GP17_CAN0_DOUT
145 CAN_TX GP18_CAN0_DIN
Notes:
1. In the Direction column, Output is from Jetson Orin NX. Input is to Jetson Orin NX. Bidir is for Bidirectional signals.
2. The direction indicated for the CAN signals are associated with that usage. The pins support GPIO functionality, so support both
input and output operation (bidirectional).
