Arduino Ethernet Shield (without PoE Module)
Overview
Note: This is a placeholder entry. Full documentation will be added when the Arduino documentation becomes accessible.
The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip. 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.
