NVIDIA Jetson Nano Developer kit was introduced in March 2019 for $99. With a quad-core Cortex-A57 processor, a 128-core Maxwell GPU, and 4GB LPPDR4 RAM, it’s a great low-cost AI platform as we wrote in our Jetson Nano getting started guide where we show how to perform inferences on still images and an RTSP video stream.
The company has now gone further in providing an affordable AI computer for developers with the launch of NVIDIA Jetson Nano 2GB Developer Kit with similar features except for the 2GB RAM, and pricing starting at $54 without a wireless adapter or $59 with 802.11b/g/n/ac WiFi 5 USB dongle. Pre-orders are open on sites like Amazon or Seeed Studio and shipping is scheduled to start at the end of the month.

As we can see from the specifications, the new developer kit does not only lowers RAM capacity to lower the price, as NVIDIA removes DisplayPort output, the M.2 socket, and PoE support. The four USB 3.0 ports have now been replaced by a 1x USB 3.0 port and 2x USB 2.0 ports, and the board now requires a 5V USB-C power supply for power. Compared to NVIDIA Jetson Nano Developer Kit-B01 launched earlier this year with two CSI camera connectors, Jetson Nano 2GB board only comes with one camera connector.
Since the M.2 socket is gone, the only option to add WiFi is by using one of the USB ports, meaning you’d be left with two USB ports to play with. The new board benefit from the software ecosystem created for the earlier boards, and you’ll find NVIDIA JetPack and resources to get started on NVIDIA developer website. The image is slightly different and optimized for low memory usage, as while it’s still based on Ubuntu it features a low memory footprint LXDE desktop environment with Openbox window manager.
