ODROID-W (Hardkernel) compatible with software for Raspberry-Pi
https://www.youtube.com/watch?v=rIZvsgXNWSc
ODROID-W is a miniature computing module which is fully compatible with all software available for the Raspberry-Pi.
The W stands for:
- Wearable device development
- Widely applicable Internet of Things (IoT) development
- Workable DIY electronics prototyping

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
