Arduino Mega is not getting electricity from the UMO Board.

Recommended Posts

Hello Guys!

Our Sainsmart replica of the UM 1.5.7 Board arrived us and the problem is very simple:

The Arduino is not getting any electricity by the UM 1.5.7 Board at all. I have to connect at least USB to it for that.

But I think the Arduino has to get its juice just over the Board.

Any suggestions for that?
