Khadas VIM3 Amlogic S922X Board to Support M.2 NVMe SSD, WiFi 5, and Bluetooth 5 Connectivity

Ever since the Amlogic S922X powered ODROID-N2 SBC launched last March, I keep reading praise for the processor and board which both deliver great performance at a relatively low price. Hardkernel was the only company that sold such a board so far, but this is about to change with some competition coming from Shenzhen Wesion with their upcoming Khadas VIM3 board that includes 2 to 4GB RAM, 16 to 32GB eMMC flash storage, a wireless module, support for M.2 NVMe SSD, and more.

Khadas VIM3 comes with some extra features compared to ODROID-N2 including built-in eMMC storage (instead of external flash), an M.2 socket supporting NVMe SSD, built-in WiFi and Bluetooth, a MIPI-DSI connector, and a few other features like an accelerometer and larger SPI flash. VIM3 is also quite smaller compared to ODROID-N2.

The company did not expand on software support at this stage, except they will provide Fenix Script, a “one-click” script for building Linux distributions.

Khadas VIM3 is coming soon, but pricing has not been announced yet. One thing for sure is that it will be more expensive than the $63/$79 ODROID-N2 simply because of the extra features such as built-in storage which you need to purchase separately for the Hardkernel board. More details may be found in the “launch page“. It’s very likely an Amlogic S922D version will be launched as well, since the company mentions “next generation, deep-neural-network applications, at 2.5 TOPS“.
