The Jetson Nano is not as easy to setup as a Raspberry Pi. There isn’t a “NOOBS” SD card you can buy, stick into your Nano and be done. But then again, this ain’t a Raspberry Pi : if you’re playing with a Jetson Nano you obviously intend to work on stuff that’s too hardcore for a Raspberry Pi, and therefore it’s safe to assume you’re not afraid of the command line prompt.
