The company will provide Android 8.1, Ubuntu 16.04/18.04, and Debian 9 for the board, but at the time of writing the information has yet to be posted on their Download page. Gyrfalcon Lightspeeur SPR2801S NPU on Orange Pi 4B should be using the same SDK as Orange Pi AI Stick Lite USB neural compute stick since it’s connected to one of  Rockchip RK3399 processor’s USB 3.0 interfaces.

The price of Orange Pi 4B is really impressive, as last year you’d have to pay about the same price just with the USB stick. Orange Pi 4 is also good value as at $49.90 it’s the cheapest Rockchip RK3399 board with 4GB RAM. For comparison, FriendlyELEC NanoPi M4 is also $50 but with only 2GB RAM, while Pine64 RockPro64 starts at $59.99 with 2GB RAM. Both are available with 4GB but at around $80.
