W5100 Ethernet Shield for Arduino with Micro SD Card Slot

The W5100 Ethernet Shield is a reliable network expansion board designed to add internet capabilities to your Arduino-based projects. Using the Wiznet W5100 chip, this module supports a full TCP/IP stack and connects easily to a LAN or the internet via a standard RJ-45 Ethernet port.

Perfect for smart devices and automation systems, the shield enables your Arduino to act as a web server, remote client, or IoT device. With full compatibility with the Arduino Ethernet library, it offers a hassle-free setup even for beginners.

A key feature is the built-in Micro SD card slot, which allows for onboard data logging. Whether you’re storing sensor data or serving HTML files, this added functionality makes your project more powerful and flexible. It’s compatible with the Arduino SD library and can work simultaneously with the Ethernet functions.

The stackable shield design allows it to sit neatly on top of Arduino Uno, Mega, or compatible boards. Long header pins allow other shields to be used alongside it, giving your projects full expandability. Status LEDs provide visual feedback for network connection and data activity.
