Core Features

High-Performance Embedded Computing
The Pentium III processor combined with a 133 MHz front-side bus provides sufficient computing power for complex real-time logic, data processing, and control algorithms, meeting the requirements of industrial automation, defense, aerospace, and test systems.

High-Speed Bus and Flexible Expansion
The VME64x bus supports burst transfer rates of up to 160 MB/s, while the Universe IIB bridge enables transparent PCI-to-VME communication. The PMC expansion slot allows functional expansion, such as additional Ethernet interfaces, serial ports, or dedicated control modules.

Rich I/O and Storage Capability
With dual Ethernet, multiple serial ports, USB, IDE, and video interfaces, the SBC supports local data caching, offline operation, and human-machine interaction, adapting to a wide range of system architectures.

Remote Management and High Reliability
Support for remote network boot, watchdog supervision, and ECC memory verification (model-dependent) ensures system stability, fault recovery, and remote operation and maintenance, making the platform suitable for long-term mission-critical applications.
