Arduino Ethernet Shield R3 Arduino Eth Shield

Add on module for your Arduino mainboard mainboard not supplied Operating voltage 5V supplied from an Arduino board Ethernet controller W5100 with internal 16K buffer Connection speed 10100Mb Once youve bought your first main Arduino board its time to start adding additional functionality with the use of extra modules referred to as shields. The Arduino Ethernet Shield connects your Arduino project to the Internet in just a few minutes. Simply plug this module onto your Arduino board connect it to your network with an RJ45 cable not included and follow a few simple instructions to start controlling your world through the Internet. As always with Arduino every element of the platform hardware software and documentation is freely available and open source. This means you can learn exactly how its made and use its design as the starting point for your own circuits.The on board Wiznet W5100 Ethernet chip provides a network IP stack capable of both TCP and UDP. It supports up to four simultaneous socket connections. Use the Ethernet library from the Arduino website 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.This most recent revision of the board exposes the 1.0 pinout on rev 3 of the Arduino UNO board. The Ethernet Shield has a standard RJ 45 connection with an integrated line transformer and Power over Ethernet enabled. There is also an onboard 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 micro SD card reader is accessible through the SD Library. The shield also includes a reset controller to ensure that the W5100 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 6 pin serial programming header is compatible with FTDI USB cables. It features support for automatic reset allowing sketches to be uploaded without pressing the reset button on the board. When plugged into a FTDI style USB adaptor the Arduino and Ethernet shield are powered from the adaptor.
