Keyestudio W5500 Ethernet Shield Ethernet Control Expansion Board for Arduino (Without POE)

The Keyestudio W5500 Ethernet Shield allows you to quickly connect your Arduino projects to the internet to build custom network applications. It is an ideal addition for students, educators, and makers looking to create simple web servers or control digital and analog pins remotely.

Seamless Arduino compatibility

This shield is fully compatible with both Keyestudio UNO R3 and Mega 2560 R3 development boards. It features a stackable design, allowing you to plug it directly onto your main controller and even stack additional expansion boards on top.

Hardware TCP/IP protocol stack

Powered by the W5500 chip, the shield supports high-speed SPI communication and hardwired TCP/IP protocols including TCP, UDP, ICMP, IPv4, ARP, IGMP, and PPPoE. It features an embedded 10/100Mbps Ethernet physical layer and supports up to eight independent socket connections simultaneously.

Onboard microSD card storage

The expansion board includes a self-popping mini SD card slot that supports up to 1GB of storage. This allows you to easily read and write files, making it perfect for storing local web pages, sensor logs, or network configuration files.

Robust and flexible design

Operating at 3.3V with 5V-tolerant I/O ports, the shield safely interfaces with standard 5V Arduino boards. It features an RJ-45 network interface, standard 2.54mm pitch female headers, and four 3mm mounting holes for secure physical installation.
