W5100 Ethernet Shield for Arduino with Micro SD Card Slot

The W5100 Ethernet Shield for Arduino with Micro SD Card Slot is a versatile expansion board that enables your Arduino projects to connect to wired Ethernet networks and store or log data via a micro SD card. Designed to stack directly on top of Arduino boards such as the Uno or Mega 2560, it uses stackable headers for a secure and compact connection, allowing seamless integration into your electronics projects.

The shield features a W5100 Ethernet controller, providing reliable and high-speed wired network connectivity through a standard RJ45 port. The onboard micro SD card slot allows for file storage, data logging, or even serving web pages over the network, making it ideal for IoT applications, home automation, or data monitoring systems. Communication with the Arduino is handled via SPI, ensuring efficient data transfer and compatibility with existing Arduino libraries.

Built-in indicator LEDs provide visual feedback for link status, network activity, and operational status, making troubleshooting and monitoring simple. Fully compatible with the Arduino IDE and the Ethernet library, this shield allows users to implement web servers, clients, and other network-based applications with ease.
