Ethernet Shield for Arduino (W5200, SPI, microSD)

The Ethernet Shield for Arduino equips your development board with reliable wired network connectivity and external data storage. Featuring a W5200 hardwired TCP/IP controller and an onboard microSD slot, it is well suited for students, hobbyists, and makers building networked IoT applications.

W5200 hardwired TCP/IP controller

The shield features an integrated W5200 chip that manages network protocols directly in hardware. This reduces processing overhead on the host Arduino board for smoother multitasking.

Eight simultaneous hardware sockets

With support for 8 independent hardware sockets, the shield handles multiple concurrent connections. This allows projects to communicate with several network endpoints at once.

Standard RJ45 networking interface

An onboard RJ45 connector enables direct, stable wired Ethernet connections to your local network. It provides a dependable alternative to wireless networking for critical data transfer.

SPI bus interface

The shield connects to the host Arduino using a standard SPI communication interface. This ensures efficient data exchange while preserving other GPIO pins for sensors and peripherals.

Integrated microSD card storage

A built-in microSD slot provides local mass storage for project assets and data logging. You can store network configuration files, serve web pages, or record incoming telemetry directly to memory.
