With the new K3931-N mITX motherboards, Kontron presents worthy successors to the Gemini Lake series and thus expands its portfolio of compact and energy-saving motherboards with the Made in Germany seal.

The mITX boards rely on the Intel Core i3 and Intel N-series (Alder Lake N) processors, setting new standards in the power range from 6W to 15W and featuring numerous improvements and new features compared to the previous series. The motherboards offer scalability in terms of performance, power consumption and cost within one product design and are available in four variants with different CPUs at

Equipped with the latest UHD Gen12 graphics, they use the same efficient cores based on the Xe architecture. In combination with up to 32 execution units, accelerated deep learning inference and media processing for various edge applications are supported by Intel AVX2 and Intel Deep Learning Boost.

With up to three display ports V1.4a, one embedded display port V1.4b (4K) and one dual-channel LVDS (24 bit), the boards support a maximum of three independent displays with 4K resolution. In addition to interfaces such as GPIO, four COM ports and four USB 3.2 Gen2, the Alder series has expansion slots for PCIe and two M.2 ports. Furthermore, the K3931-N mITX supports ccTalk and uses a SODIMM socket for high-performance DDR5 memory with up to 32 GB.
