Hi,

i know there is some difficulti in powering the boards from usb but has anybody ever done it

Only my MB_USB module is powered from USB   :wink:

(And my notebook does not even deliver enough current for the MB_USB  :()

USB only delivers 500 mA at 5V! This is not enough if you use a LCD with backlicht…
