Arduino Mega is not getting electricity from the UMO Board.

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?

Greets.

There is a single jumper labeled "CARD_PWR" located close to the electronics cooling fan output. The jumper needs to be present for both boards to share power.

Thank you xisle, I already found that.

Sainsmart just totally forgot to solder on that jumper socket. I did and it worked fine.
