ODROID.

“ODROID-W is a miniature computing module which is fully compatible with all software available for the Raspberry-Pi.”

The ODROID-W measures a very small 60 x 36 x 7mm (2.4 x 1.4 x 0.3”). new features and improvements over the original Raspberry Pi:

– Li+ rechargeable battery charger and fuel gauge for portables, wearable and robots application
– Real Time Clock to keep accurate time without an Internet connection by just adding a coin battery
– 12-bit precision ADC to measure the dynamic voltage signals via two single-ended inputs
– DC/DC step-down converters for higher power efficiency
– DC/DC step-up converter for 5Volt rails (USB host and HDMI) from a Li-Polymer battery
– USB Host port can be placed on top or bottom as preferred
– DIY friendly 0.1inch/2.54mm pitch IO connector (up to 32 GPIO ports) for handy prototyping

ODROID-W = RPI + RTC + ADC + UPS + Battery gauge with significant Minimalism

There seem to be some unknowns about this, MAKE has a post & Pi forum posts here.
