One of the most interesting announcements from NVIDIA's 2019 GTC conference is the launch of the NVIDIA Jetson Nano, the latest arm-developer board with a Tegra SoC. This developer board is different from previous Jetson boards in that it targets a very affordable price point: only $ 99.
NVIDIA Jetson developer boards have been hundreds of dollars in the past, or in the case of the latest high-performance offering, the Jetson AGX Xavier has a price of $ 1,299. The Jetson Nano costs only $ 99, although the performance obviously does not match that of the AGX Xavier. The Jetson Nano Developer Kit is passively cooled, but there is a 4-pin fan head on the circuit board and there are holes on the aluminum heatsink if you want to mount a fan for better cooling.

The Jetson Nano also offers 4GB of LPDDR4 memory, gigabit Ethernet, 12 MIPI tracks, four USB ports and can control up to two simultaneous displays. With these features and the Maxwell graphics card, the nano capabilities can be way ahead of most (or even all?) Arm developer boards for the under $ 100 market. The advantage of using the older Tegra X1 design is that the support of the open source Linux kernel is better than that of the recently released SoCs, and there is even open source Tegra Maxwell graphics support in the Nouveau driver stack ,  Unlike the high-end Jetson boards with eMMC memory, the Jetson Nano relies on a microSD card for storage. Developer kit connectivity includes four USB 3.0 A ports, HDMI 2.0, DisplayPort 1.2, a 40-pin header, a MIPI CSI camera port, a micro SD slot, an M.2 wireless slot, and Gigabit Ethernet. One of the shortcuts on this board is that there is no integrated Wi-Fi, but if you're interested in wireless connectivity, an external card is required.
The Jetson Nano supports CUDA, TensorRT and the other software components of the higher Jetson boards; The same JetPack software runs on the Nano. The "Linux 4 Tegra" on the Jetson Nano targets Ubuntu 18.04 LTS, although other Linux distributions have added support for other Jetson boards.
Overall, the $ 99 Jetson Nano is a very compelling product, and we've had some preliminary benchmark results in our lab.
