The BeagleBone is the low-cost, high-expansion focused BeagleBoard using a low cost AM335x Cortex A8 ARM processor. It is similar to the earlier BeagleBoards and can act as a USB or Ethernet connected expansion companion for your current BeagleBoard and BeagleBoard-xM or work stand-alone. The BeagleBone is small even by BeagleBoard standards and with the high-performance ARM capabilities you expect from a BeagleBoard, the BeagleBone brings full-featured Linux to places it has never gone before.
BeagleBoard-xM is based on the TI DM3730 and delivers increased perfromance over the BeagleBoard and is based on an ARM Cortex(TM) A8 processor running at 1 GHz with extra memory @ 512MB of low-power DDR RAM, enabling hobbyists, innovators and engineers to go beyond their current imagination and be inspired by the BeagleBoard.org community. 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.
The USB-powered BeagleBoard is a low-cost, fan-less single board computer that unleashes laptop-like performance and expandability without the bulk, expense, or noise of typical desktop machines.
