DescriptionThe Ethernet W5100 Shield is an expansion board designed to add Ethernet connectivity to Arduino boards. It features the Wiznet W5100 Ethernet controller chip, which enables the Arduino to connect to local area networks (LAN) or the internet using the Ethernet protocol. Additionally, it comes with a Micro SD card slot, allowing the Arduino to read and write data to/from a Micro SD card.
Key features of the Ethernet W5100 Shield for Arduino include:Wiznet W5100 Ethernet Controller: The W5100 chip handles the Ethernet communication and provides the necessary hardware support for TCP/IP protocol stack.
RJ45 Ethernet Connector: This allows you to connect the Arduino to a wired network using an Ethernet cable.
Micro SD Card Slot: The shield comes with a slot to insert a Micro SD card, which can be used to store and retrieve data, log information, or serve as a storage medium for various applications.
SPI Interface: The W5100 communicates with the Arduino board via the Serial Peripheral Interface (SPI) protocol.
Stackable Design: The shield can be stacked on top of the Arduino, allowing you to add other shields or modules on top of it, further expanding its capabilities.
Power over Ethernet (PoE) Support: Some versions of the Ethernet W5100 Shield might support Power over Ethernet (PoE), which allows the board to receive power through the Ethernet cable, simplifying the power supply setup.
To use the Ethernet W5100 Shield with your Arduino board, you will typically stack the shield onto the Arduino, making sure to align the pins correctly. You can then use the Ethernet library provided by the Arduino IDE to write sketches that utilize the Ethernet functionality. This allows you to create applications that can communicate with other devices or servers over the network and access the internet.
The Micro SD card slot can be accessed using the appropriate libraries, allowing you to read from and write to the Micro SD card just like you would with any standard SD card.
Applications:Web Server: Use the shield to create a web server that can serve web pages and data over a local network or the internet. This is useful for displaying real-time data, status updates, or remote control interfaces.
IoT Applications:Develop IoT devices that can send and receive data over the internet. This could include temperature and humidity monitoring, smart home automation, and environmental sensing.
Data Logging: Create data logging systems that record sensor data and store it on a server or a cloud service for later analysis.

Very useful shield for LAN connections, but I'got one with no mac address. Sd-card slot onboard to keep logs/configs, etc.
Reasonable shipping time; fits properly on my Arduino. Might update when I attempt to turn it on soon.
a must have. Great for controlling all your projects.
Works just fine so far.***WARNING***Make sure that the I/O pins set inside completely. You have to put some pretty firm pressure on it.I was debugging for hours trying to figure out why it wasnt working but it was just because the pins were sitting in all the way....Hope this helps
This shield is compatible with Arduino UNO R3. No additional library files needed. Much cheaper than an original Ethernet shield from Arduino.
LOVE IT. Fast shipping. Complete compatible.
Appears to work as well the original. I have used both the ethernet features (using the original Arduino ethernet library), as well as the micro SD card slot with great success.
I ran some test programs, and they work fine.
great for the price! slow shipping tho.
