Batuino: Battery-friendly Arduino compatible board

The Batuino is a battery-friendly Arduino compatible board. It can be powered from one cell of Li-ion rechargeable battery or up to three cells of alkaline batteries. An on-board USB port is used to power, program, and charge simultaneously.

What inspired you to make this project?:
