WIZnet W5100 Network Module with Mag Jack - WIZ811MJ
Product ID: 314

WIZnet's WIZ811MJ works as a breakout board for their W5100 embedded TCP/IP chip. Also included on the board is an RJ-45 MagJack connector (RJ45 with X’FMR). It can be used as a component and little effort is required to interface to the W5100. The WIZ811MJ is an ideal option for users who want a simple solution to adding TCP/IP capability to their project.

There is no on-board regulation, so you'll need to supply clean/regulated power sources. All pins of the W5100 are broken out to two pairs of 10-pin, 0.1" pitch headers.

For detailed information on implementation of Hardware TCP/IP, refer to the W5100 Datasheet.
