OpenSprinkler Forums Hardware Questions USB to power wifi Reply To: USB to power wifi



I tried hooking up the tp-link wireless relay using a usb type-a cable, female to female usb adapter and a usb to micro-usb cable.  It ran ok last night, but it seemed to be a bit haywire today.  The display was flickering a bit and went blank after a minute or two.  I tried restarting several times.  After removing the USB load, it seems to have cleared up.  Maybe the two cables + adapter drew a little too much current for the unit…  rj
