Product Introduction:
This Ethernet Shield which is based on the Wiznet W5100 Ethernet Chip gives you an easy way to get your Device Online. It is directly supported by 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 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.
