==Introduction==
W5100 is a multi-purpose single internet interface chip, integrated 10/100 Ethernet controller inside, and applied to embedded system which is high integration, high stability, high performance and low cost. <br>
It can be connected to Internet without operating system and compatible with IEEE802.3 10BASE-T and 802.3u 100BASE-TX. <br>
It contains TCP/IP protocol stack that is full-hardware and verified by market for years, Ethernet medium transport layer and physical layer.<br> 
You don’t need to consider the Ethernet control, and just need simple program for ports.<br>
The module should be connected to the SPI communication interface on EASY plug control board with only one cable, so the wiring is rather simple.
 
<span style=color:red> '''Special Note:''' <br>
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface. <br> If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module. </span><br>

<br>

==Specifications==
* Various interface: Direct Bus, Indirect Bus and SPI Bus
* Supporting TCP/IP protocol stack of hardware, also TCP, UDP, ICMP, IGMP, IPv4, ARP and PPPoE 
* Up to 4 independent ports
* Integrating 16KBYTE transmit-receive cache
* Supporting automatic conversion of polarity
* Coming with Internet access
<br>

==Technical Details==
* Dimensions: 61mm*30mm*18mm
* Weight: 14.1g
<br>

==Connect It Up==
Connect the EASY Plug W5100 Ethernet module to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

==Upload the Code==
Copy and paste below code to [http://wiki.keyestudio.com/index.php/How_to_Download_Arduino_IDE Arduino IDE] and upload.   <br>
<span style=color:red> '''Note:''' before compile the code, do remember to place the necessary libraries inside the libraries directory of Arduino IDE. </span><br>
You can download the libraries from the link: https://drive.google.com/open?id=18_Ye5Ew1TrpnBsLUO4J9rvEqqoUL-DJG

==What You Should See==
Done uploading the test code, open the serial monitor and set the baud rate to 9600;<br>
you should be able to check the IP address that W5100 Ethernet module connected.
