ETHERNET SHIELD W (FOR UNO R3, LEONARDO R3, MEGA R3) IN JOHANNESBURG

The W Ethernet Shield is fully compatible with Ardunio Ethernet Shield and Ethernet library and allows an Arduino board to connect to the internet. It is based on the Wiznet W Ethernet chip which provides a network (IP) stack capable of both TCP and UDP. It supports up to four simultaneous socket connections. 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. Arduino uses digital pins , and 13 (SPI) to communicate with the W 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 W and the Arduino board. It adds a micro-SD card slot, which can be used to store files for serving over the network. The micro-SD card slot can be accessed using the SD library. It is compatible with the Arduino Duemilanove (168 or 328), Uno as well as Mega () Informational LED's: 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 MAC address: 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }       Courier via Aramex Courier.
