Arduino Ethernet Shield 2

The Arduino Ethernet Shield 2 connects your Arduino to the internet in mere minutes. Just plug this module onto your Arduino Board, connect it to your network with an RJ45 cable (not included) and follow a few simple steps to start controlling your world through the internet. As always with Arduino, every element of the platform - hardware, software and documentation - is freely available and open-source which means you can learn exactly how it's made and use its design as the starting point for your own customized circuits. Hundreds of thousands of Arduino Boards are already fueling people's creativity all over the world, every day.

*Requires an Arduino Board (not included).

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.

The most recent revision of the board exposes the 1.0 pinout on rev 3 of the Arduino UNO Board (Jameco P/N: 2151486).

The Ethernet Shield 2 has a standard RJ-45 connection, with an integrated line transformer and Power over Ethernet enabled.

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 current Shield supports a Power over Ethernet (PoE) module designed to extract power from a conventional twisted pair Category 5 Ethernet cable.

Features
