Description

We’re carrying the WIZnet WIZ811MJ module to support the Adafruit Ethernet Shield Kit. It’s an assembled and tested breakout board for the W5100 ethernet chip that has a built-in TCP/IP stack. What’s that mean? It talks networking, so you don’t have to know how (or know that much to make it work).

Please note that these modules are unlike XPort XBee modules, these communicate over SPI (not serial), and don’t have a built-in DHCP client.

Features

• Plug-in module
• Usable without H/W design for W5100, Transformer and RJ-45
• Available of fast evaluation of W5100 and MCU in the target board
• Supports MCU BUS and SPI Interface
• Supports Auto MDI/MDIX (auto detection of crossover)
• Supports network status indicator LEDs – FDX, TX, RX, Link, Collision
