Mini W5100 LAN Ethernet Shield Network Module

WIZnet W5100 Ethernet / Network Module
W5100 is a set of TCP / IP protocol, MAC and PHY in one network chip, with support for direct bus interface, SPI bus.

See HOW-TO WIKI PAGE here  which includes links to the Schematic diagram and W5100 Data sheet

The built-in Ethernet Arduino IDE library is designed directly for W5100 and is supported on this product. Your Arduino can be a Web Server with this brick!

There is on-board regulation, so you can use  5-12V VCC input. The signal pins  support 3.3V / 5V operation level.
