World’s smallest i.MX6 module has onboard WiFi, eMMC

Variscite unveiled a 50 x 20mm “DART-MX6″ module that runs Linux or Android on the Freescale i.MX6, with up to 64GB eMMC flash and -40 to 85°C support. Variscite’s claim that the 50 x 20mm DART-MX6 is the world’s smallest computer-on-module based on Freescale’s i.MX6 system-on-chip appears to be a valid one.

It’s also just a hair larger than Variscite’s own 52 x 17mm DART-4460, which is based on a dual-core TI OMAP4460 SoC, and Gumstix’s slightly larger 58 x 17mm Overo modules, which use TI Sitara AM37xx SoCs.

We’ll be tracking the progress of Ubuntu Phone with interest – it surely must get better than this – but this first device is one to write off to experience. Read more
