Welcome to the Ethernut Project

If you think the Internet is World Wide Web and email only, you will miss the exciting world of Embedded Ethernet Devices. How about controlling and monitoring your electronic devices from any place in the world, directly, without using a PC? Whether it's a simple LED, a complex robot or your complete home:

Ethernut can do it!

This is an Open Source Hardware and Software Project for building tiny Embedded Ethernet Devices.

Hardware

Several Open Source Reference Designs are available, based on 8-bit AVR as well as ARM7 and ARM9. All schematics and the CAD data are published as Open Source Hardware and may be freely used for private or commercial purposes. More...

Firmware

The target software is an Open Source implementation of a Real Time Operating System called Nut/OS and a TCP/IP protocol suite named Nut/Net. Several application examples are provided, including an embedded Webserver, a simple RS232 to TCP/IP gateway and an Internet Radio playing MP3 streams. More...

Tools

The GNU cross compiler toolchain is a collection of free programming tools, which can be used to create Nut/OS firmware binaries for AVR and ARM targets on a PC running Linux, Windows or Mac OS X. The ImageCraft IDE for Windows is a low cost, commerciallly supported alternative. More...
