The Ethernut 5 is a single-board computer and webserver with an ARM9 CPU. Atmel's AT91SAM9XE512 CPU provides a large number of peripherals, like 10/100Mbit Ethernet, USB 2.0, CMOS image sensor, SDcard/SDIO/MMC, IrDA, I2S, ADC, TWI and SPI. Like other members of the Ethernut family, the board provides an extension connector for attaching additional hardware. This board therefore is suitable for prototyping your own hardware design or being directly integrated into your final product.
The integrated Flash memory can be protected against external access and is complemented by 1GB NAND Flash, 128MB SDRAM and 4MB serial Flash. This may be further increased by using the MMC/SDcard slot.
For power supply, a conventional DC input of 7-24V is available. Alternatively, the USB or Ethernet cable may be used as well. Flexible power management is done by a dedicated ATmega168 CPU. The real-time clock is backed up by a double-layer capacitor.

Software Application development is done in the high-level programming language C, using free GNU tools. An active Open Source community created Nut/OS, a cooperative RTOS with TCP/IP stack specially designed with low memory consumption in mind. The well documented and tested code provides a convenient, portable API. Programmers familiar with C for desktop PCs will soon feel comfortable with its standard C library functions. Although well pre-configured for Ethernut 5.0, an easy-to-use graphical interface is available on Linux, Windows and OS X PCs to adapt the system to special requirements with just a few mouse clicks.
In addition to Nut/OS, the Linux operating system is available for Ethernut 5. One available board support package is based on the Ångström distribution. Ethernut 5 comes ready to use with a pre-installed Linux BSP based on the Yocto Project.
Support Several companies with many years of experience in Nut/OS software and Ethernut hardware offer commercial support. Furthermore, mailing lists are an important element of this Open Source project, where developers use each other's experience to help solving respective problems.
License All Nut/OS target source code as well as the hardware design are published under the permission-free BSD License and can be used in commercial products for any purpose without license fees. In contrast to some other Open Source license models, it does not require you to publish your own source code enhancements.
