XNUT-100 Embedded communication computer with Ethernet

After 10 years in production we decided to consolidate our two XNUT offerings and to discontinue the XNUT-100 model.

Please consider the compatible XNUT-105 instead!

Given the source code and hardware compatibility between XNUT-100 and XNUT-105 it should be just a matter of re-compilation to migrate your application to our XNUT-105 module which is almost identical but has a different MCU and an additional CAN port.

XNUT-100 single board computer (SBC)
Ethernet interface RS-485 port RS-422 port RS-232 port

XNUT-100 is an Ethernet single board computer module with industrialized form-factor, DIN-rail enclosure and connectivity options like RS-232, RS-422 and RS-485 interfaces. A CAN version is available as XNUT-105.

XNUT-100 is based upon the AVR ATmega128 CPU as it's core and the free open source RTOS and TCP/IP stack Nut/OS.
