AI Experience: Speedy But Sometimes Odd Results Obviously, the whole process would be easier for beginners if the software was all preloaded on Linux4Tegra, but using the command line to download and install programs is a typical part of the Linux development experience. Perhaps not surprisingly, the AI software and demos that Nvidia recommends in its documentation aren’t in a store and need to be downloaded, compiled and invoked from the command line. The look and feel of the desktop are the same as on standard Ubuntu Linux, and there’s a huge ecosystem of Linux apps, from development software to games that are available from the bundled “Software” app, which is a kind of app store. The official operating system for the Jetson Nano and other Jetson boards is called Linux4Tegra, which is actually a version of Ubuntu 18.04 that’s designed to run on Nvidia’s hardware. So, unless you’re building Jetson Nano into a mass-produced product, the developer kit is your only choice. By the way, if you want the $129 board, Nvidia says that you’ll need to order 1,000 or more units to get it at that price. Considering that Nvidia also makes a standalone Jetson Nano compute unit, which costs $129 and has 16GB of on-board storage but no ports, it makes sense that the developer kits’ processor would also be on an add-in board. Though our review unit came put together, it’s easy to see that the CPU and GPU are actually on a separate board that plugs into a 260-pin SODIMM slot on the main PCB that houses the ports and connectors. When the $10 Raspberry Pi Zero W has built-in Wi-Fi / Bluetooth that just work out of the box, it’s hard to justify Nvidia’s decision to leave it out of a computer that costs 10 times as much. ![]() ![]() There may be other dongles that are easy to find or compile drivers for - Nvidia recommends the $10 Edimax-7811UN (opens in new tab) - but you shouldn’t have to go through this kind of hassle just to connect to the Internet, let alone pair with a Bluetooth keyboard. In the office, we had a TP-Link Archer AC600 T2UH USB Wi-Fi adapter and I spent two to three hours hunting down instructions on how to compile its driver for Jetson and trying different methods before I gave up and decided to stick with Ethernet. Either way, the version of Ubuntu 18.04 that the Jetson Nano uses does not come with built-in drivers for Wi-Fi adapters and, according to all the support documentation I read, the only way to get them is to compile your own. You can use either a USB dongle or an M.2 Wi-Fi card that lives in the M.2 slot that’s buried beneath the CPU and GPU (more on that later). Attaching a third-party Wi-Fi dongle isn’t as easy as you might think.
