Ethernet Shield – W5100 / W5500
```The Ethernet Shield is designed to add wired Ethernet networking capability to Arduino-compatible development boards. It connects to the microcontroller through the SPI interface and provides an RJ45 Ethernet port for connecting projects to a local network or the Internet.
This shield is available in two controller variants: the W5100 and the newer W5500. Both controllers provide hardware-based TCP/IP networking and 10/100 Mbps Ethernet connectivity, making them suitable for applications such as web servers, networked sensors, remote monitoring, IoT systems and automation projects.
The shield follows the Arduino Shield form factor and can be stacked directly onto compatible Arduino boards. The W5500 version offers a larger internal socket buffer and improved networking capabilities compared with the W5100, making it a useful choice for projects requiring multiple simultaneous network connections or more efficient Ethernet communication.
The Ethernet Shield is suitable for Arduino Mega, Arduino Uno and other compatible boards that provide the required SPI interface and shield-compatible headers. Software libraries and pin assignments may vary depending on the controller and specific shield revision.
