The first Wandboard development boards launched in 2012 nearly 5 years ago based on Freescale i.MX6 Solo and Dual processor, with Wandboard Quad launched a few months later. The boards were fairly popular at the time due to their better specifications, and especially Freescale’s much better documentation and software compared to the competition such as Broadcom (Raspberry Pi) and Allwinner (Cubieboard). Since the boards are based on TechNexion EDM system-on-modules they could also be used by companies working on their own products based on the system-on-module. It’s also a good platform if you want to test various version of Android, because the company released Jelly Bean, Kitkat, Lollipop, and Marshmallow images for the boards, and I’m expecting a Lollipop version soon.
However, albeit the company worked on other NXP boards such as PICO-IM6UL Android Things, there had not been any hardware upgrade for Wandboard for nearly 4 years, but last month Wandboard QuadPLUS was released with NXP i.MX 6QuadPlus processor boasting a faster GC2000+ GPU, an upgrade to 802.11ac WiFi and Bluetooth 4.1 connectivity, the addition of a power management IC, and a fix for HDMI EDID + CEC.

Beside Android, the board can also run Ubuntu, and Linux built with the Yocto Project. The company also introduced an official camera module for the board with CAM-OV5645 module based on Omnivision OV5645, and supported in Linux 4.1.15 and greater.
Wandboard QuadPLUS is sold for $139, CAM-OV5645 camera module for $25 directly on TechNexion website. The price of older boards have also been reduced by $10. You’ll find more details on Wandboard.org with firmware and source code downloads, a Wiki page, and forums, but most information has not been updated to include QuadPLUS board.
