Geekcreit® Ethernet Shield W5100 With Mega 2560 For Arduino

Ethernet Shield W5100: It is directly supported by Arduino official Ethernet Library. It adds a micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Duemilanove (168 or 328) UNO as well as Mega (1280/2560) and can be accessed using the SD library. The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. It supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which connect to the internet using the shield.
