Nominated by the trade magazine Elektronik for the ‘Product of the Year’ 2025, the K4021-U mSTX motherboard from Kontron scores with the latest DDR5 memory technology, Intel graphics, and a new integrated NPU for dedicated AI acceleration.
The motherboard, which is available from Rutronik, supports up to four 4K60 HDR displays or two 8K displays simultaneously. The platform thus represents a significant advance in embedded computing technology and meets the requirements for the most demanding AI, industrial, and medical applications. When volume production begins in 2025, a matching SMARTCASE chassis kit solution will also be available. In addition, suitable cooling solutions, memory modules and high-performance SSDs for the motherboard are also available from Rutronik.
The compact, flat, and versatile design is ideal for applications with limited space and a good alternative to 3.5-inch or NUCs. The energy-efficient design, wireless installation, easy maintenance and flexible expandability make the K4021-U mSTX a particularly cost-effective solution.
The platform was developed for 24/7 continuous operation and is designed for operating temperatures from 0 to +60°C. The use of high-quality components and strict lifecycle management also ensure high quality and long-term, reliable use.
Robust connectivity and expandability
Designed with expandability in mind, the K4021-U mSTX motherboard features four M.2 slots for storage and Wi-Fi modules, as well as numerous connection options, including two COM ports, Thunderbolt 4, USB 3.2 Gen2, and GPIO. This allows the board to be customised for a wide range of industrial applications.
Cutting-edge performance thanks to Intel Core Ultra processors
Performance and efficiency are based on the latest Intel Core Ultra 7 and 5 processors, which are part of the Meteor Lake U SoC family. The integrated Neural Processing Unit (NPU) extends AI capabilities and enables a 20x optimisation of performance-per-watt. This makes it ideal for image recognition or automation applications.
