Ethernet shield instantly enables internet connectivity for arduino projects. An on-board wiz5100 ethernet controller handles up to four tcp and udp connections, just stack it onto an arduino to create your own networked devices. Easily check connection status with on board indicator lights. Extend your design further with two extra rows of pin header that connect to shields and prototyping boards.
