Not really a problem.
Ethernet Board on UNO or vise versa.
Today I got a new Arduino UNO and Arduino Ethernet Board. Both original ! In my case the UNO fits on top of the Ethernet Board.
It doesn't mater for the funktion ( I think ). I only wonder when I saw pictures on the Web > Ethernet Board is on top of the UNO ...
Anybody who know whats happen ?
