I have a project that uses a netpro-vx, wifi module FCC, verdex pro XM4, and a roboaudio-th board.  What is the best way to power this package?  Trying to drive everything from the power pins of the roboaudio board appears to be inadequate as the WIFI and Ethernet connections have problems staying connected - even with an 8 amp 5 volt supply feeding it. Is there a good place to apply power to the robostix and Ethernet boards separately?
