TechNexion Wandboard Dual was one of the first Freescale i.MX 6 single board computers when it launched in early 2013 and the company has introduced a few more models over the years including Wandboard QuadPlus in 2017.
TechNexion is now working on a new version called Wandboard 8MPLUS powered by the recently announced NXP i.MX 8M Plus SoC that features a built-in 2.3 TOPS NPU for AI acceleration.
Wandboard 8MPLUS preliminary specifications:

The company will officially support Android and Yocto Linux for the board, but if history is any guide, many other operating systems may eventually be supported as was the case for Wandboard.
The highlight of the board is really the NPU inside NXP i.MX 8M Plus processor, so just after providing an overview of the board, Marcel vandenHeuvel, TechNexion CEO, showcases an AI demo with Tensorflow Lite where object recognition is done in around 8ms when the NPU is enabled or about twenty times faster than with the CPU alone.
The demo runs on a full-featured i.MX 8M Plus development board as Wandboard 8MPLUS SBC is quite not quite available yet.
But TechNexion is now taking pre-orders for two variants of the board:
- Wandboard IMX8M-Plus-2G with 2GB LPDDR4 for $134.00
- Wandboard IMX8M-Plus-4G with 4GB LPDDR4, Wi-Fi and Bluetooth connectivity for $159
There’s no clear ETA, and the company promises to ship the board as soon as NXP i.MX 8M Plus processor is mass-produced. The latter often happens roughly one year after the announcement, so around January 2021. Bear in mind that processor launch timing is highly variable, so it could be a few months earlier or later.
