SKU: DFR0125
The DFRduino Ethernet W5100S Shield connects Arduino to the Internet via RJ45. It uses WizNet W5100S chip, integrating full TCP/IP stacks and 4 hardware sockets. Communicate with it/SD card via SPI (ICSP pin). Supports Arduino UNO/Mega. V3.0 upgrades from W5100: lower power, less heat, better performance.

This sample shows how to get network time from the NTP time server. Upload the sample, and open the serial monitor to see the time.
2. Example Code for Arduino-View IO Status Web Server
This sample turns UNO into a Web server that other devices in the same LAN can access to view IO status.
3. Example Code for Arduino-Control IO Status Web Page
This sample allows other devices on the same LAN to control the status of IO2 and IO3 via the Web page.

FAQ
Hi. I have bought 2 of these but none have the MAC Address stick.
How can I get it?
Thanks
Hi
The official library Ethernet.h manage W5100 chip, and Ethernet2.h manage W5500 chip, if you using this board, you don't need to use Ethernet 2 library, Ethernet.h is good for using.
1. Open the Control Panel -> Network and Internet -> Network and Sharing Center -> Change Adapter Settings
2. Find the network to which you are connected -> right-click -> Properties -> Find "Internet Protocol Version 4 (TCP/IPv4)" in the Network TAB and double-click to access properties settings
3. Change the IP address to make the computer IP address and the controller IP address are in the same LAN
Use it as the normal one using Arduino SD library is ok. Note that because the W5100 and SD card share the SPI bus, only one can be active at a time. For more, please check on Arduino, Arduino Ethernet Shield.
Check whether the switch or router supports DHCP, if not, set an IP address by specifying an IP address. Please refer to more Ethernet libraries and tutorials.
