It now comes clear why those future Jetsons have a green rocket ship: the were sponsored by Nvidia all the time, perhaps all their gadgets were as well -Nvidia Rosie household robot?
The cheapest Nvidia to play around with is the 2GB model of the Jetson Nano [missed chance for Nvidia: should have been called 'Elroy', but perhaps Hanna-Barbera would not concede].
The 2GB Jetson Nano is a stepped-down version of the $99 4GB model that is offered for prices as low as $59 and that is powered by a (relatively low-cost) 5V 3A USB-C adapter, such as you use with the Raspberry Pi 4. What do you get for those $59 (USA) / £66.99 (UK) [-pure theft, that price: $59 is £44.70] / €89.99 (EU) [-again pure theft, that price: $59 is €49.85]
- A quad-core Arm Cortex-A57 CPU @1430 MHz,
- A NVIDIA Maxwell GPU with 128 CUDA cores,
- 2GB 64-bit LPDDR4, 1600MHz / 25.6 GB/s,
- One USB 3.0 Type-A, 2 USB 2.0 Type-A, 1 USB 2.0 Micro-B,
- A 40 GPIO header, 12-pin power/UART header,
- 4-pin fan header,
- A Gigabit Ethernet RJ45 jack,
- A full-size HDMI 2.0 port.
The Nano 2GB kit just comes with the board and a quick start guide. What you don't get is a PSU or a SD card -you need that, the 2GB version has no onboard eMMC-Jetpack SDK and the Nvidia Deepstream SDK-, and you might need additional cooling.
The passive cooling block has mounting holes for a 40x40mm fan, but those who really want to run things cool will go for the Nvidia Nano version of the 52Pi ICE Tower Cooling Fan -or mount a 40mm to 120mm Vertical Fan Adapter Converter...
The people who want to blow $30 on cooling, instead of a Waveshare fan of a mere $5, can of course also go for the $99 model and a 5V/4A PSU.
