Ethernet W5100 Shield Network Expansion Board w/ Micro SD Card Slot for Arduino
The Arduino Ethernet Shield enables your Arduino board to connect to the internet, leveraging the Wiznet W5100 Ethernet chip. This chip provides a complete network (IP) stack that supports both TCP and UDP protocols, making it ideal for internet-based projects. The Ethernet W5100 Shield also features a Micro SD card slot, allowing you to store or retrieve files over the network, and supports up to four simultaneous socket connections.
To get started, you can use the Ethernet library to write sketches that connect your Arduino to the internet. The shield is designed to connect to your Arduino board via long wire-wrap headers, ensuring the pin layout remains intact, and it allows you to stack additional shields on top without interference.
