About ethernut.de

Ethernut is an open source hardware and software project for building small embedded Ethernet devices. It publishes reference board designs based on 8-bit AVR and on ARM7 and ARM9 processors, with schematics and CAD data released as open source hardware.

The firmware side consists of Nut/OS, an open source real-time operating system, and Nut/Net, a TCP/IP protocol suite. Application examples include an embedded web server, an RS232-to-TCP/IP gateway and an internet radio that plays MP3 streams. A GNU cross-compiler toolchain is provided for building Nut/OS firmware on Linux, Windows and Mac OS X.

The project targets developers who want to control and monitor electronic devices over the network. The download area offers Nut/OS beta and stable releases, and the project has published a Git repository. The news section lists releases dated from 2010 to 2014.

Product: Ethernut open source hardware reference boards and the Nut/OS real-time operating system with Nut/Net TCP/IP stack.
