11.3 CAN
Jetson TX2 NX brings a single CAN (Controller Area Network) interface out to the main
connector.
Table 11-6. Jetson TX2 NX CAN Pin Description
Pin # Module Pin Name Tegra X2 Signal Usage/Description
Usage on DevKit
Carrier Board
Direction Pin Type
145 (CAN_TX) RSVD CAN0_DOUT CAN Transmit
Optional CAN header
Output CMOS – 3.3V
143 (CAN_RX) RSVD CAN0_DIN CAN Receive Input CMOS – 3.3V
Notes:
1. In the Type/Dir column, Output is from Jetson TX2 NX. Input is to Jetson TX2 NX. Bidir is for Bidirectional signals.
2. The directions for the CAN signals is true when used for that function. Otherwise as GPIOs, the directions are bidirectional.

11.4 Fan
Jetson TX2 NX provides PWM and Tachometer functionality for controlling a fan as part of the
thermal solution. Information on the PWM and tachometer pins/functions can be found in the
following locations:
 Jetson TX2 NX Module Pin Mux:
• This is used to configure GPIO14 for FAN_PWM and GPIO08 for FAN_TACH. The pin used
for
FAN_PWM is configured as PM3_PWM3. The pin used for FAN_TACH is configured as a
GPIO.
