Some of the more popular pages on JetsonHacks are the pinouts for the GPIO headers on each of the Jetson developer kits. Here’s a new one for the Xavier NX!
The Jetson Xavier NX GPIO J12 Header Pinout gathers together some of the information that’s spread over several documents such as the sysfs number for the GPIO pins, I2C bus numbers and the device of the UART and places it in one place. Plus there’s a bunch of fun colors!
You will need a NVIDIA Jetson Xavier NX Developer Kit, of course.
