Basic questions

Sorry for the misunderstanding I will go back and investigate further. I just did not think it would be as difficult since each board I will be powering will be getting there power from the lipo's through the existing plug that is designed for a wall wart, so I figured if I just supplied 5v to them they would be fine as they have the step down converters on the board. But i guess that logic was way off. THanks again and I will post back once I figure out the proper info.
