New in stock is the amazing BeagleBone! It's the low cost, high-expansion hardware-hacker focused BeagleBoard for people that love embedded Linux systems. Basically a bare bones BeagleBoard, it can run all by itself or act as a USB or Ethernet connected expansion for your current BeagleBoard or BeagleBoard-xM.
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 (Angstrom) to places it has never gone before.
At over 1.5 billion Dhrystone operations per second and vector floating point arithmetic operations, the BeagleBone is capable of not just interfacing to all of your robotics motor drivers, location or pressure sensors and 2D or 3D cameras, but also running OpenCV, OpenNI and other image collection and analysis software to recognize the objects around your robot and the gestures you might make to control it.
Through HDMI, VGA or LCD expansion boards, it is capable of decoding and displaying multiple video formats utilizing a completely open source software stack and synchronizing playback over Ethernet or USB with other BeagleBoards to create massive video walls.
If what you are into is building 3D printers, then the BeagleBone has the extensive PWM capabilities, the on-chip Ethernet and the 3D rendering and manipulation capabilities all help you eliminate both your underpowered microcontroller-based controller board as well as that inefficient PC from your basement.
