12.5 Fan
Orin module provides PWM and Tachometer functionality for controlling a fan as part of the
thermal solution. Information on the PWM and Tachometer pins and functions can be found in
the following locations:
 Orin Module Pin Mux
• This is used to configure GPIO14 (PWM) for FAN_PWM and GPIO08 for FAN_TACH. The pin
used for FAN_PWM is configured as GP_PWM6. The pin used for FAN_TACH is configured
as a GPIO.
 Orin (SoC) Technical Reference Manual (TRM)
• Functional descriptions and related registers can be found in the TRM for the FAN_PWM
(PWM chapter).
