Introducing BeagleBoard – Perfect for Hobbyists as the Basis for Building More Complete Systems

The BeagleBoard-xM is a low-power open source hardware single-board computer. It delivers extra ARM Cortex -A8 MHz at 1 GHz and extra memory with 512MB of low-power DDR RAM, enabling hobbyists, innovators and engineers to go beyond their current imagination and be inspired by the community. It is also ideal for educational purposes that can be used around the world to teach or learn open source hardware and open source software capabilities. Designed with the community inputs in mind, this open hardware design improves upon the laptop-like performance and expandability, while keeping at hand-held power levels. Direct connectivity is supported by the on-board four-port hub with 10/100 Ethernet, while maintaining a tiny 3.25″ × 3.25″ footprint.
