I've been experimenting with xbees and have been powering them from the 3.3V pin of arduino's. I just realized that the 3.3V pin can only deliver 50 ma. (I had stupidly assumed it had capabilities similar to the 5V pin.) The arduino's seem to be functioning fine along with the xbee radios so if I'v…

aargh. Have I done damage? (xbee powered from arduino 3.3V pin)
