$25 ODROID-C0 Development Board Targets IoT, Wearables, Robots and Drones
Hardkernel started to mention ODROID-C0 board last November, a cost-down and smaller version of ODROID-C1+ board powered by Amlogic S805 quad core Cortex A5 processor with 1GB RAM, dropping Ethernet, and a few USB port, but gaining a Li-po battery management unit. The company has now officially launched the board, which can be purchased for $25 on Hardkernel website or via distributors such as Ameridroid.

In case you need WiFi, the company provides a 802.11b/g/n 1T1R USB dongle with antenna, but you could probably use your own too, and the board runs Ubuntu 14.04 with OpenGLES, and Android 4.4.x both relying in Linux 3.10, which happens to be exactly the same as ODROID-C1/C1+ since all three boards are software compatible. You can find OS images, source code, and documentation in the Wiki, or directly access ODROID-C1 user’s manual.
There are several unpopulated connectors to make the board more compact and light for drones or robotic projects, but for people who do need the connectors, Hardkernel also sells a connector pack for $1.80, which you’ll need to solder yourself.
