SparkFun WIZnet W5100 Network Module WIZ811MJ

WIZnet's WIZ811MJ functions as a breakout board for their W5100 Embedded TCP/IP chip. The board also features an RJ-45 MagJack connector (RJ45 with X'FMR). It can be used as a component and requires minimal effort to interface with the W5100. The WIZ811MJ is an ideal option for users looking for a simple solution to add TCP/IP capabilities to their project.

There is no onboard regulation, so you must use clean and regulated power sources. All pins of the W5100 are arranged in two pairs of 10-pin 0.1-inch headers.

For detailed information on implementing hardware TCP/IP, please refer to the W5100 datasheet.
