Two tastes that taste great together: Arduino and Ethernet. But until now the only way to connect an Arduino to the Internet via a LAN was to add an Ethernet Shield. Wouldn't it be great if there was an Arduino-compatible board with on-board Ethernet? Better still, what if that board was based on the Freetronics Eleven and the Freetronics Ethernet Shield (with Power-over-Ethernet support!) but merged together into a single, integrated board that was 100% Arduino compatible and network-enabled.

This, folks, is what you've been waiting for:
The EtherTen is a 100% Arduino compatible board that can talk to the world. Do Twitter updates automatically, serve web pages, connect to web services, display sensor data online, and control devices using a web browser.

The Freetronics EtherTen uses the same ATmega328P as the Duemilanove and the same Wiznet W5100 chip used by the official Arduino Ethernet Shield, so it's 100% compatible with the Ethernet library and sketches. Any project you would previously have built with an Arduino and an Ethernet shield stacked together, you can now do all in a single, integrated board.

We've even added a micro SD card slot so you can store web content on the card, or log data to it.


  • Gold Plated PCB
  • Top and bottom parts overlays
  • Top-spec ATmega328P MCU
  • Mini-USB connector
  • D13 Pin isolated with a mosfet so you can use it as an input
  • Power-over-Ethernet support
  • Ethernet activity indicators on the PCB and the jack
  • 10/100 base-T auto-selection
  • Fully compatable with standard Ethernet library
  • Reset management chip
  • Fixed SPI behaviour on Ethernet chipset
  • Robust power filtering
