The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W***0 ethernet chip (datasheet). The Wiznet W***0 provides a network (IP) stack capable of both TCP and UDP. It supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which 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 another shield to be stacked on top.

The Ethernet Shield has a standard RJ**5 connection, with an integrated line transformer and Power over Ethernet enabled.

The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving over the network.

It is compatible with the Arduino Uno and Mega (using the Ethernet library). The onboard microSD card reader is accessible through the SD Library. When working with this library, SS is on Pin 4.

The latest revision of the shield also includes a reset controller, to ensure that the W***0 Ethernet module is properly reset on power-up. Previous revisions of the shield were not compatible with the Mega and need to be manually reset after power-up. The original revision of the shield contained a full-size SD card slot; This is not supported.

The *-pin serial programming header is compatible with FTDI USB cables and the Sparkfun and Adafruit FTDI-style basic USB-to-serial breakout boards. It features support for automatic reset, allowing sketches to be uploaded without pressing the reset on the board. When plugged into a FTDI-style USB adapter, the Arduino and Ethernet shield are powered off the adapter.

The current shield has a Power over Ethernet (PoE) module designed to extract power from a conventional twisted pair Category 5 Ethernet cable:

1, IEEE**2.3af compliant

2, Low output ripple and noise (**0mVpp)

3, Input voltage range *6V to *7V

4, Overload and short-circuit protection

5, 9V Output

6, High efficiency DC/DC converter: Typ *%@********************, ***0V isolation ( to output)

The shield does not come with the PoE module built in, it is a separate component that must be added on.

Arduino communicates with both the W***0 and SD card using the SPI bus (through the ICSP header). This is on digital pins *1, *2, and *3 on the Duemilanove and pins *0, *1, and *2 on the Mega. On both boards, pin *0 is used to select the W***0 and pin 4 for the SD card. These pins cannot be used for general I/o. On the Mega, the hardware SS pin, *3, is not used to select either the W***0 or the SD card, but it must be kept as an output or the SPI interface won't work.

The shield provides a standard RJ*5 ethernet jack.

The reset on the shield resets both the W***0 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

**0M: Indicates the presence of a **0 MB/s network connection (as opposed to *0 MB/s)

RX: Flashes when the shield receives data

TX: Flashes when the shield sends data

COLL: Flashes when network collisions are detected
