I have a Arduino Mega 2560 R3 is it posible to make it work with a Ethernet SHield R2 with PoE?
or R3 versions only work with R3 version shields?
Sorry for the Question i am noob and i have search on google but there are a lot of examples of Mega 2560 R2 with ethernet shield r3 but not the other way.
The R2 Ethernet Shield should work fine on the R3 Arduino MEGA 2560.
