Jetson Nano GPIO Header PINOUT

PRELIMINARY

Jetson Nano J41 Header Layout. Last Edited: April 15, 2019

I2C and UART pins are connected to hardware and should not be reassigned. By default, all other pins (except power) are assigned as GPIO. Pins labeled with other functions are recommended functions if using a different device tree.

Notes

  • 3-25-19 – Preliminary. Formal signal names may be incorrect (I2C), missing descriptions and colors are incorrect.
  • Added Bus information for I2C
