Ethernet Shield - W5100
We've been disappointed with the cost of ethernet shields for some time now so we've done something about it. This Arduino compatible ethernet shield uses the standard W5100 ethernet IC and is as easy to get working with standard libraries and code.
Requires an Arduino board (not included)
Operating voltage 5V (supplied from the Arduino Board)
Ethernet Controller: W5100 with internal 16K buffer
Connection speed: 10/100Mb
Connection with Arduino on SPI port
