Hi all, I'm new on this forum and on Arduino concepts. I'm interested to buy Arduino Mega 2560 rev.3 (A000067) and Arduino Ethernet Shield(A000056) on RS site. I want to know if there could be problems of compatibility between them (exactly between A000067 and A000056), or I've just to plug ethernet shield onto Arduino Mega 2560 without problems. I don't have found more about this on internet. Thank's a lot!!
