Keyestudio W5100 Ethernet Shield Board with SD Card Slot Original Chip Compatible With Arduino UNOR3 /Mega 2560R3/DUE/1280

The Keyestudio W5100 Ethernet Shield Board provides an easy way to connect your Arduino projects to the internet, turning your development board into a simple web server. This shield is ideal for South African students, educators, and makers looking to explore IoT, remote monitoring, and network-connected robotics.

Easy internet connectivity

This shield allows you to turn your Arduino into a web server or use the internet to read and write to its digital and analogue inputs and outputs. It is directly supported by the official Arduino Ethernet Library for straightforward coding.

Onboard storage expansion

The board features an integrated mini SD card slot, supporting both read and write operations for TF cards. This allows you to store web assets, log sensor data, or load configuration files directly from local storage.

Stackable and compatible design

Designed to be fully compatible with the Arduino Uno R3, Mega 2560 R3, Due, and 1280 control boards. The stackable design means you can plug it directly into your Arduino and stack other shields on top of it.

Status monitoring and control

The shield is equipped with multiple LED indicators for power, network connection, and communication status, along with an onboard D13 LED. A dedicated physical reset button is also included for easy hardware restarts.

Flexible network integration

Featuring a standard RJ45 network connector, this shield supports TCP/IP protocols for reliable wired network communication. Note that the MAC address is random and can be easily defined within your Arduino sketch code.
