OK so the nominal supply voltage is +5V. But what\'s the absolute minimum? Presumably the device doesn\'t stop working at 4.9V. How low can you go?
I ask because it would be nice to be able to power an RPi from 4 NiMH rechargeable cells, which only have a nominal voltage of 1.2V per cell or 4.8V for the pack, and that\'s at full charge. Will this work?
