Ethernut Single Board Computer Product Guide
Low-cost Ethernet capability can be added to many embedded applications.
Since its introduction in the year 2000, Ethernut boards have been used to
develop some of the most innovative products. Using the hardware, firmware,
software and tools, developers have everything they need to develop leading
networked devices rapidly and affordably. The board is well suited for
application development in a wide range of applications. Some areas are:
- Networked sensors
- MP3 streaming
- Remote monitoring equipment
- Alarm service provision
- Remote diagnose and service
- Home automation and building control
