If you're using python, you're most likely going to be interfacing with the Jetson using the RPi library. Here's the documentation for the python RPi.GPIO module.

• RPi.GPIO documentation
• PWM Control Tutorial through RPi.GPIO

It's also possible to interface with the GPIO pins through the filesystem as linux exposes them as a virtual file system.

• A c++ GPIO guide that uses the filesystem, the associated github repo.
