Arduino Ethernet Shield (Wiznet W5100)

 

Connects your Arduino to the internet in a few minutes. Can be used as a server or receiver, plugs directly into Arduino boards, no soldering required. Just plug this module into your Arduino board, connect it to your network with an RJ45 cable (not included) and follow a few simple instructions to start controlling your world over the internet. As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open source. This means you can learn exactly how it's made and use its design as a starting point for your own circuits.

Directly powered by the Arduino official Ethernet Library. It adds a micro-SD card slot that can be used to store files to be served over the network. Based on the Wiznet W5100 Ethernet Chip, the Arduino Ethernet Shield provides an easy way to get your Arduino Online.

Arduino Duemilanove (168 or 328), Uno and Mega (1280) /2560) and can be accessed using the SD library. Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. Supports up to four simultaneous socket connections.
