💻 Product Overview

An Ethernet shield built on the Wiznet W5100 chip that lets an Arduino board connect to a network over TCP or UDP. It handles up to four simultaneous socket connections and can act as either a server or a client, so a board can serve simple web pages or send data online. A micro SD card slot adds file storage for content served across the network.

✨ Key Features

W5100 network stack: The Wiznet W5100 chip provides an IP stack supporting both TCP and UDP.
Four sockets: Up to four simultaneous socket connections can be open at once.
Server or client: The board can operate as a network server or as a client.
Micro SD slot: A micro SD card connector stores files for serving over the network.
Stackable headers: Long wire-wrap headers keep the pin layout intact so another shield can sit on top.
No soldering: The shield plugs directly onto a compatible board.
