Here’s some setup notes for the Jetson Nano
Install the latest Jetson SD card image from https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit#write to a microSD card. At least a 16GB card is recommended. The download image is 6GB.
The Jetson Nano can draw quite a bit of power if you push it hard. It is recommended to get a decent 4A supply and populate J48 with a shorting jumper. See this excellent post here
