Variscite DART-MX6 is a Tiny SoM with Freescale i.MX6 SoC, Wi-Fi and Bluetooth

Orange Pi Development Boards

Variscite has unveiled what they claim to be the world’s smallest i.MX6 SoM with DART-MX6, a 50x20mm system-on-module featuring Freescale i.MX6 dual or quad processor, up to 1GB RAM, up to 32GB eMMC flash, as well as a wireless module for Wi-Fi and Bluetooth connectivity. Other small i.MX6 modules include TechNexion PICO-iMX6, or SolidRun microSoM found in Hummingbird board, and DART-MX6 has indeed the smallest area among the three.

The company provides support for the Yocto Project (Daisy with Linux 3.10.x), Ubuntu, and Android 4.4, and documentation and source can be found on DART-MX6 wiki with most links pointing to resources for their VAR-SOM-MX6 module so both are likely to be software compatible.

For evaluation and to speed early development, a development kit called VAR-DVK-DT6 can be used. It is composed of VAR-DT6CustonBoard baseboard populated with DART-MX6, a 7″ LCD display with capacitive touch, and relevant cables and accessories, as well as documentation and design package.
