# OFFICIAL ARDUINO ETHERNET SHIELD

> -

Original author: Eliot (source: https://hackaday.com/2008/11/06/official-arduino-ethernet-shield/)

## Components

- **WIZnet W5100** x 1 ([docs](https://docs.wiznet.io/Product/Chip/Ethernet/W5100))

## Article

**HOW TO USE**

Arduino has just released an [official ethernet shield](http://arduino.cc/en/Main/ArduinoEthernetShield). It’s based on the same WizNet W5100 chip that was used in the [tiny ethernet board](https://hackaday.com/2008/10/17/tiny-arduino-ethernet-board/) we covered earlier. The W5100 handles the full IP stack and can do TCP or UDP with four simultaneous sockets. The board has a power indicator plus six LEDs to debug the connection. It works with the standard [ethernet library](http://arduino.cc/en/Reference/Ethernet). The reset button resets the shield and the Arduino. The SD adapter is not currently supported by the [Arduino software](http://www.mahalo.com/Arduino_Hacks).
