The Arduino Ethernet is a microcontroller board based on the Arduino Uno, and incorporating a WizNet W5100 TCP/IP Embedded Ethernet Controller.
Get started making tiny Arduino projects with the Ardweeny Starter Pack! There's no need to leave your full Arduino board in your project since it's great for prototyping, just drop in an Ardweeny which is about 1/3 the cost and much, much smaller.
The Ardweeny Prototype Pack gives you the ability to get your Ardweeny project figured out before you make the giant leap of soldering it all together for it's final presentation. Think of this pack as the scrimmage before the big game!
The Freeduino is based on the open source project version of the Arduino Diecimila. We've adapted the design for more convenience as a semi-kit!
If you just want to dip your toe in the waters of FreeduinoLand (which is actually also known as "The Fabulous Republic of Arduino"), this basic bundle is what you're looking for.
