Modular open source hardware meets the BeagleBoard. The BeagleTouch eliminates the need for many of the peripherals typically required to interface with the BeagleBoard single board computer.

With a 480×272 resolution and 262K color touchscreen OLED display, a 20 mm speaker, and a type B-mini interface to RS232 serial, the BeagleTouch snaps directly onto the BeagleBoard to create a handheld tablet computer.

Instead of searching for 6 different cables to connect a desktop full of monitors, keyboards, mice- not to mention FTDI, null modem, and IDC cables required for serial communication, the BeagleTouch allows embedded software programmers to get right to prototyping and custom application development.

Combined with the BeagleJuice battery pack, the BeagleTouch and Beagleboard becomes a laptop-like, Linux-powered device that simplifies embedded hardware development for almost any application.
