Description: The Arduino Ethernet Shield 2 allows an Arduino Board to connect to the Internet. It is based on the Wiznet W5500 Ethernet chip. The Wiznet W5500 provides a network (IP) stack capable of both TCP and UDP. It supports up to eight simultaneous socket connections. Use the Ethernet library to write sketches that connect to the Internet using the Shield. The Ethernet Shield 2 connects to an Arduino Board using long wire-wrap headers extending through the Shield. This keeps the pin layout intact and allows another Shield to be stacked on top of it.
There is an onboard micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Uno and Mega (using the Ethernet library). The onboard micro-SD card reader is accessible through the SD Library. When working with this library, SS is on Pin 4. The original revision of the Shield contained a full-size SD card slot; this is not supported.
The shield also includes a reset controller, to ensure that the W5500 Ethernet module is properly reset on power-up. Previous revisions of the Shield were not compatible with the Mega and needed to be manually reset after power-up. The most recent revision of the board exposes the 1.0 pinout on rev 3 of the Arduino UNO Board. The Ethernet Shield 2 has a standard RJ-45 connection, with an integrated line transformer and Power over Ethernet enabled but please be aware that this shield does not come with a built in PoE module. The PoE module that will need to be added on is a separate component that must be added on. This shield also features several TinkerKit input/output and communication interfaces that can be found on the topside of the board.

It´s amazing product for the proyects
Setting up mini-server for test purposes. Samples gave me a good start. The file support on SD is a great feature. I mated it to a Mega board.
Great board, as good or better than previous versions.
If you’re having trouble getting this to work, make sure you’re using the Ethernet2 library, which ships with Arduino IDE 1.7.6. You’ll find the example code in the Examples menu and it should work right out of the box.
Newest versions are at: http://www.arduino.org/software . Arduino.cc is behind the times, offering 1.6.5 at the time of this writing.
Hi, running 1.7.6 is probably going to be a necessity, but both 1.7.6 and 1.6.5 are currently the latest versions. One is provided by Arduino.org, the other by Arduino.cc and have different features. Because this shield is made by Arduino.org you will need their version to get the example code. It is not so much that Arduino.cc is behind the times, but that Arduino.cc and Arduino.org are currently working against each other instead of with (which is unfortunate for you the customer).
