keyestudio W5100 Ethernet Shield gives you an easy way to get your Arduino Online.
It can turn your Arduino into a simple web server or use the Internet to read /write its digital and analog outputs/inputs.
It is directly supported by Arduino official Ethernet Library. It also supports the read &write of mini SD card (TF card).
The shield adopts stackable design. You can directly plug it to Arduino board. It's also compatible with our other shields.
Adds a micro-SD card slot, can be used to store files for serving over the network

Description

Description:
Just plug this module onto your Arduino board, connect it to your network with an RJ45 cable (not included) and follow a few simple instructions to start controlling your world through the internet.

Specification:
Requires an Arduino board (not included)
Operating voltage 5V (supplied from the Arduino Board)
