Reset pins in place
This short will also reset the CPU from shutdown, causing the Pi to start.
Get Power to the Pi on the Move
HACK 18
Power doesn't have to mean a plug in the wall. You have a few more op-
tions to increase portability.
To get power to your Pi, you need five stable volts at 700 mA through a Type B Micro
USB plug. As mentioned elsewhere, it's not a bad idea to get a power adapter specif-
ically intended for the Raspberry Pi, though your phone charger or other similar
adapter will likely work.
Less-than-Recommended Power Options
Much like trying to substitute anything for eggs in a recipe, there are options
that aren't particularly recommended but work out for some people. For
example, powering your Pi through your laptop's USB port. It doesn't offi-
cially work and isn't recommended, but we've seen it work. Trying to push
power through the GPIO isn't a great idea either. See “Get Power Through
GPIO Safely” on page 26 for more on power and the GPIO pins.
We've also heard of success with power over Ethernet and even intentionally
backpowering through USB to power the Pi. Again, not the recommended
