I'm pretty new to the Arduino setup. Just got my Arduino Uno and now am thinking about getting the Ethernet Shield to expand the number of applications I can do. My question is: Is the Arduino Uno and Ethernet Shield compatible? In the link http://www.arduino.cc/en/Main/ArduinoEthernetShield
, it doesn't list the Uno as one of the boards compatible with the micro SD card slot. Also, since it seems like sparkfun.com doesn't have the Ethernet Shield in stock, I wanted to get it on amazon.com. However, should I be worried about the board version? How can I tell if I am getting the most up-to-date hardware? I don't see any version numbers on the board itself.
