W5100 R3-2013 Ethernet Shield for Arduino

The W5100 R3-2013 Ethernet Shield for Arduino enables Arduino boards to connect to an Ethernet network through the Wiznet W5100 chip. It provides an IP network stack with TCP and UDP support and supports four simultaneous socket connections. The shield includes a standard RJ45 Ethernet connection, an onboard micro-SD card slot for file storage, and a reset controller for proper module reset at power-up. It also includes an INT jumper for interrupt notification wiring.

More Info

• The SPI bus is shared between the W5100 and the SD card.
• Only one of the shared SPI devices can be active at a time.
• Pin 10 is used to select the W5100.
• Pin 4 is used to select the SD card.
• On Duemilanove boards, SPI communication uses pins 11, 12, and 13.
• On Mega boards, SPI communication uses pins 50, 51, and 52.
