W5100 Ethernet Shield for Arduino

Description

With the W5100 Ethernet shield, it is very easy to design internet connected circuits and to build the internet of things. It is based on the W5100 ethernet controller which provides an implementation of the network stack (IP) with TCP and UDP capability.

This shield is compatible with Arduino and it also includes an SD card slot, connected to the same SPI bus as the W5100 ethernet controller.
