Mouser is now shipping the highly anticipated BeagleBoard PocketBeagle. This minuscule yet complete open source USB-key-fob computer from BeagleBoard.org provides extensive flexibility, enabling makers and designers to add only the peripherals they need.

The device is based on the power-packed 1GHz Octavo OSD3358-SM, the smallest SiP device in the OSD335x family. The 21mm × 21mm SiP includes 512mb of DDR3 RAM. Prioritizing ease-of-use, this affordable Linux computer features a simple, intuitive design that offers tremendous expansibility. The device, bolstered by two 32-bit PRUs with single-cycle input/output (I/O) latency, enables rapid prototyping for 3D printing, robotics, and education. Also included in the ultra-tiny board is an SGX530 graphics accelerator.

The device has 72 expansion pin headers with power and battery I/Os, eight analog inputs, 44 digital I/Os, high-speed USB, and numerous digital interface peripherals. For reinforced power and security management functions, the board is supported by the Arm Cortex-M3 processor. The device also offers an SD/MMC connector for MicroSD as well as a high-speed USB 2.0 OTG (host/client) micro-B connector. The computer is compatible with all BeagleBone software not requiring access to unavailable expansion pins.
