efus™
Highly integrated SoM for easy carrier board design
efus – Easy. Functional. Universal. Scalable.
With over 20 years of project experience, we know that carrier board costs and development costs are a critical factor in embedded development. That’s why we introduced efus, which ensures cost-effective and layout-friendly base board design.
The key advantages of the efus standard are:
-
Easy to integrate: Optimized pinout and MXM-2 connector for simplified carrier board routing
-
Functional: Rich set of interfaces for flexible application needs
-
Universal: Suitable for a wide range of embedded use cases
-
Scalable: Adaptable performance and memory options for various requirements
Additional highlights:
-
Compact form factor (47x62mm) for space-saving designs
-
Standardized MXM-2 connector ensures reliable integration
-
Designed for industrial, medical, and HMI environments
