XNUT-105 Embedded communication computer with Ethernet and CAN

XNUT-105 single board computer (SBC)
Ethernet interface CAN (Controller Area Network) port RS-485 port RS-422 port RS-232 port

XNUT-105 is an Ethernet single board computer with industrialized form-factor, DIN-rail enclosure, CAN interface and additional RS-232, RS-422 and RS-485 ports.

XNUT-105 is based upon the AVR AT90CAN128 CPU as it's core and the free open source RTOS and TCP/IP stack Nut/OS.

By using the freely available GNU GCC tool chain for Windows or Linux and the open source RTOS and TCP/IP stack Nut/OS, developers can quickly create custom Protocol Converter, Web Server and Fieldbus Gateway devices.

The perfect solution for equipment manufacturers who want to integrate a Controller Area Network (CAN) into the world of Ethernet and TCP/IP .

Development

Applications are developed in the C programming language using the free AVR-GCC compiler toolchain on either Windows or Linux development hosts.

Nut/OS' architecture has been focused on portable standards. Developers with experience in C programming and TCP/IP applications for the PC will soon feel confident. Existing software can be adapted for Nut/OS with minimal effort.

The Nut/OS operating system offers a feature rich API including:

At the same time Nut/OS is a very lean OS which is well suited for microcontroller CPUs and their small memory footprint. Typically more than 100 KB program space and 20 KB data memory are available for your application. Nut/OS comes with several sample applications, including an embedded web server and a RS-232 to Ethernet gateway.
