TWIZ5200 - 

PICtail™ Plus W5200 Ethernet Daughter Board
WIZnet’s W5200 Ethernet PICtail™ Plus board provides 10/100Mbps, half/full duplex Ethernet connectivity by onboard WIZnet W5200 Ethernet controller, which has a hardwired TCP/IP processing engine. The board has both PICtail headers and PICtail Plus side-edge connectors designed to be plugged into the Explorer 16 (DM240001), PIC32 I/O Expansion Board (DM320002), PICDEM.net 2 (DM163024), PIC18 Explorer (DM183032), and other supported development boards. It supports both Microchip’s software TCP/IP Stack and WIZnet’s hardwired TCP/IP Stack simultaneously on PIC18, PIC24, dsPIC and PIC32 platforms. The Hardwired TCP/IP Stack especially fits well for Simple Internet connectivity for PICs with small program memory size like the PIC16.
