Beaglebone Black is the most recent incarnation of the Beaglebone open source hardware platform. For less than $50, the board includes Ethernet, graphics processing, 4Gb of nonvolatile storage, and ports supporting USB, HDMI, and Beaglebone's custom I/O add-ons, called "capes". Here's how to run some simple commands to toggle digital I/O on the board!
