I think the BBB is the better choice as well, but you'll likely want to measure real-world power consumption.
Neither board is really designed as a mobile platform, but the Pi is at heart a set-top box (powered by AC), while the BeagleBone has it's roots in tablet-like processors and has fine-grained control over powering up/down different parts of the chip, CPU speed, etc. I'm not sure on the Pi if you can disable it's probably power-hungry GPU that is actually in control of the system (the ARM core is actually a secondary CPU, the black-box GPU runs the show). There are also likely some tweaks to be made with the BBB that will reduce power consumption, specifically putting the HDMI Tx chip in a power-down state. The on-board eMMC will also probably help with power consumption, or at least help a bit with reliability (no uSD connector to cause problems). Finally, the BBB is actually engineered to be able to run off battery, which is very similar to what you want to do, while I don't know if the Pi has a means to work with multiple power sources. Anyway, best of luck, and ask here if you go with the 'Bone and run into any problems! On 4/12/2014 3:05 PM, Philip Polstra wrote: > BBB is a clear winner.
