Details

Use the 5V 4A DC input to deliver stable power when running extra peripherals beyond micro‑USB limits.

Designed for Jetson Nano 4GB boards (A02/B01/SUB) and not intended for Jetson Nano 2GB or Jetson Orin Nano.

A dedicated 5V 4A supply helps support higher-load setups such as fans, cameras, and displays.

Higher-current DC power reduces power-limit issues during demanding applications and extended testing.


Follow the official guidance for DC input by setting the J48 jumper on A02/B01 boards; SUB boards don’t require a jumper.


A 5.5 x 2.5 mm DC plug connects to the Jetson Nano barrel jack and is compatible with 5.5 x 2.1 mm ports.
