PocketBeagle

PocketBeagle is an ultra-tiny-yet-complete open-source USB-key-fob computer. PocketBeagle features an incredible low cost, slick design and simple usage, making PocketBeagle the ideal development board for beginners and professionals alike.

PocketBeagle® is a 33mm by 55mm single board computer that can be programmed through a web browser. Much smaller than BeagleBone Black®, this tiny key-fob sized computer still packs nearly all of the same features. Whether you are using PocketBeagle® in a CubeSat, a robotics project, a 3D printer, IoT device, drone, or a hand held gaming device, this SBC is flexible and small enough to take on any challenge.

Built around a 1-GHz Linux computer and 2 powerful 200 MHz hard-real-time programmable real-time microcontrollers, PocketBeagle® offers a robust amount of computer power for such a small footprint.  The SPI, UART and USB expansion capabilities makes adding Ethernet, Bluetooth, and WiFi easy with already available Linux drivers. You can also add an SPI-based display, loads of different sensors, cameras, or motor controllers for any application.
