Module Pin
Pin # Name Orin Signal
230 GPIO14 GP31_PWM3
208 GPIO08 GP62
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 GPIO014 and GPIO08 is associated with their use as Fan PWM/Tach. The pins support GPIO
functionality, so support both input and output operation (bidirectional).
