W5200 Ethernet Shield
W5200 Ethernet Shield is compatible with Official Arduino Ethernet Shield and support fast SPI and 8 sockets.
These are PCB files for the W5200 Ethernet Shield for Arduino. The files were created in the free & low cost EagleCad software available from CadSoft.
You need to change the existing W5100 files to W5200 library files.
Install W5200 library Overwrite w5100.cpp, w5100.h to the "/libraries/Ethernet/utility" folder in your Arduino IDE.
Using the W5200 library and evaluate existing Ethernet example. In the Arduino IDE, go to Files->Examples->Ethernet and open any example, compile and upload the file to Arduino board.
Note: libraries/Ethernet/Ethernet.h needs the following at line 10 instead of #define MAX_SOCK_NUM 4, since it doesn't #include "w5100.h" anymore:
#define MAX_SOCK_NUM 8
#define MAX_SOCK_NUM 4
