Note: The buffers on UART0_TXD, UART0_RTS* and UART1_TXD are there to prevent connected
devices from changing the pin state during power-on. These pins are associated with SoC

CAN

Orin module 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 Orin module. Input is to Orin module. 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 b oth
input and output operation (bidirectional).
