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.
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.
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 you will need 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.
