    Power Requirements for the BeagleBone Blue

    locknutbushing

      Hi, I am using the BeagleBone Blue for a robotics project, but I have no intention of using the recommended 2-cell Lipos recommended in the documentation, as they don't have enough voltage or power output for the application. I would much rather use a step-down converter to power the board from the 3-cell Lipo that I am using for the robot. However, this begs the question: what are the power requirements? The documentation is surprisingly vague about this. The recommended battery has 7.4V and 20 amps burst, but there's also a 9-18V power jack...

       

      What are the voltage and current inputs that are enough for the BeagleBone Blue to run all four motor drivers and some other pins, but not enough to damage or brick it?
