Arduino uses digital pins 10, 11, 12, and 13 (SPI) to communicate with the W5100 on

the ethernet shield. These pins cannot be used for general i/o.

The shield provides a standard RJ45 ethernet jack.

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
