Details

Add dual-band WiFi 5 connectivity to supported NVIDIA Jetson boards through a compact USB 3.0 adapter.

Compatibility is intended for Jetson Nano B01, Jetson Xavier NX, and Jetson TX2-NX; Jetson Orin Nano / Orin NX are not supported.

On Jetson Official System (Ubuntu 18 LTS), the adapter is designed for plug-and-play use with JetPack 4.4.1 and above.

A practical fit for robotics and smart robot car projects that need reliable wireless networking in a small form factor.

Broad OS support makes it easy to use on both Linux systems and Windows PCs for development or deployment.

The mini-size design stays low-profile on a laptop or embedded build while remaining easy to carry.

Choose 2.4GHz for wider coverage or 5GHz for lower interference depending on your environment.

AC1300-class dual-band speeds support up to 400Mbps on 2.4GHz and up to 867Mbps on 5GHz.

The USB 3.0 interface is backward compatible with USB 2.0/1.1 ports for flexible installation.
