Best Budget 7th Generation Core™ Processor Based Motherboards

By understanding the context of partner request, DFI shows off latest industrial motherboards with a robust design and advanced features including 7th Gen Intel® Core™ processors, multiple memory-on-board choices, high bandwidth interfaces, and up-to-date M.2 interfaces. This enable the board to deliver increased CPU performance, visual enhancement with lower power consumption, high speed transmission, and large storage capacity to make harsh environment conditions work efficiently and successfully.

M.2 with Intel® Optane™ Memory Easily Boost Your Devices

Breakthrough technology delivers an ordinary experience such as unprecedented responsiveness and high speed performance without sacrificing the capacity of a hard disk drive.

Experience Spectacular Views : 4K UHD Technology

As graphics resolution continue to have more stunning clarity, DFI’s new products combined with 7th Generation Intel® Core™ processors allow sharper and more vivid images and video with 4K UHD technology. Simultaneously, covering from small form factor SBC to ATX allows up to 3 independent displays that increases partner possibility and flexibility of creating expansion designs on their customized build.

Running a Device on a Wide Voltage Range

The supply of voltage in different environments varies and can become unstable during operation as a result of requiring wide range power to fit the appliances. To meet diversity need, new industrial motherboard are compatible with 9~36V wide range power adapters.

Empowering Partners as DFI Quality Promise

Strict testing from thermal solution to basic component is essential to enable that DFI deliver high-quality products. Undergoing stricter test such as ESD, FloTHERMAL, and HALT maintain stability of operation in the harshest environment.

Complete Industrial Motherboard Product Line

New wide array of rugged and reliable industrial motherboards and modules, including ATX, microATX, Mini-ITX, Embedded SBC, and COM Express, will be continuously created by DFI to meet the diversity of applications.
