The NEW Arduino Ethernet Shield Rev3 is an Arduino add-on that allows an Arduino board to connect to a LAN (Local Area Network) using the Ethernet library. The library is available for free at http://www.arduino.cc New available features: * Micro SD card connector with active voltage translators *Power Over Ethernet ready (PoE module not included) *On board reset controller NOW Compatible with the Arduino MEGA board SUPPLIED WITHOUT PoE MODULE PoE stands for "Power over Ethernet". The PoE module enables obtaining power from the ethernet connector. This shield **does not** include the PoE module, so power must come from another source.
