Re: Powering the Raspberry Pi
I would be careful interfacing with the RPi, though. Micro usb powers the board with 5V in, but voltage drops to 3.3V and most of the chips on the board are regulated at 3.3V. In/out pins are unprotected, meaning that if you put a 5V signal on a pin, you might fry the pin.
