OpenSprinkler Beagle (OSBo) is an open-source sprinkler / irrigation extension board for the BeagleBone Black. It is based on the design of OpenSprinkler, but its ‘brain’ is a BeagleBone instead of an AVR microcontroller. OSBo makes use of BeagleBone’s GPIO pins to directly control sprinkler valves. By stacking a BeagleBone Black on top of OSBo, you instantly have a low-cost, web-connected sprinkler controller. OSBo is expandable — by linking OpenSprinkler Zone Expansion Boards, you can extend to an unlimited number of stations. You can also make use of the digital/analog pins of the BeagleBone Black to interface with external sensors and actuators.
