since the micro usb port does not look like it will like stage use for powering :-) what is the recommended way to hooking up a 5v source? simply supply 5v at the 5v pad (as seen in the IDE pinout)? or is there another place/pin for 5v input?
is a 7805 voltage regulator preferred over a straight 5v supply) (the former would probably have less noise in the 5v signal since it would regulate 9v or similar down to 5v)
