KitsGuru W5100 Ethernet Shield for Arduino Electronic Components Electronic Hobby Kit

The Arduino Wiznet Ethernet W5100 Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 Ethernet chip providing a network (IP) stack capable of both TCP and UDP. The Arduino Ethernet Shield supports up to four simultaneous socket connections. Use the Ethernet to write sketches which connect to the internet using the shield. The on-board micro-SD card slot can be used to store files for serving over the network. It is compatible with the Arduino Uno and Mega (using the Ethernet library). You can access the on-board SD card slot using the SD library which is included in the current Arduino build.1. It supports upto 4 simultaneous socket connection2. use the ethernet library to sketches which connect to the internet using the shieldArduino communicates with both the W5100 and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5100 and pin 4 for the SD card. These pins cannot be used for general i/o. On the Mega, the hardware SS pin, 53, is not used to select either the W5100 or the SD card, but it must be kept as an output or the SPI interface won't work.1.
