USB power?

Is it possible to use this USB breakout board as a 5 volt power supply for your microcontroller projects? If so, then do you have to use a voltage regulator?

USB won't supply a whole lot of current. Possibly limited to 100mA to 500mA depending on your USB host. Should be more than enough to run the micro itself, but if you're running much else it won't likely be enough. Especially if you're running servos or other motors.

You may be able to use a powered USB hub to get some more juice to your project, but that will still likely max out at 500mA.
