At only 17mm x 58mm x 4.2mm in size, the Overo™ Earth motherboard gives open source innovators access to the industry’s highest performance, generally available ARM®-based platform in the tiniest, lowest cost Linux computer available.

Nearly 40 percent smaller than existing Gumstix motherboards, Overo is ideal for small, hand held applications such as mobile computing, data collection, telecom, remote operations, transportation and embedded systems.

The power consumption of the Overo Earth motherboard is typically less than 1W.
