The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the WiznetW5100 ethernet chip (datasheet). The Wiznet W5100 provides a network (IP) stack capable of both TCPand UDP. It supports up to four simultaneous socket connections. Use the Ethernet library to write sketcheswhich connect to the internet using the shield. The ethernet shield connects to an Arduino board using long

wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows anothershield to be stacked on top.

The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving overh k I i ibl i h h A d i D il d M ( i h E h lib i i

The reset button on the shield resets both the W5100 and the Arduino board.

The shield contains a number of informational LEDs:

PWR: indicates that the board and shield are powered

LINK: indicates the presence of a network link and flashes when the shield transmits or receives data

FULLD: indicates that the network connection is full duplex

100M: indicates the presence of a 100 Mb/s network connection (as opposed to 10 Mb/s)

RX: flashes when the shield receives data

TX: flashes when the shield sends data

COLL: flashes when network collisions are detected

The solder jumper marked "INT" can be connected to allow the Arduino board to receive interrupt-drivennotification of events from the W5100, but this is not supported by the Ethernet library. The jumperconnects the INT pin of the W5100 to digital pin 2 of the Arduino.
