Ethernet + Micro SD Shield for Arduino

The Ethernet and Micro-SD Shield for Arduino is a versatile expansion shield designed to add wired Ethernet connectivity and local Micro-SD storage to Arduino-based systems. It integrates an Ethernet controller for reliable TCP/IP communication and an onboard Micro-SD card slot for data logging, file storage, and serving web content. The shield uses the SPI interface for communication and stacks directly onto compatible Arduino boards for easy integration. It is ideal for IoT systems, web servers, remote monitoring, and embedded networking applications.
