Previously, we have seen a 1.8" single-board computer from the embedded electronics manufacturer DFI built around the AMD Ryzen Embedded R1000 series. Now, the manufacturer has launched another industrial motherboard to the long list of 3.5" SBCs that gets the 9th/8th Generation Intel Core with Intel C246 to boost artificial intelligence analysis in mission-critical applications.

One of the differentiating features of this all-new CS551 is that it is designed to work at sub-zero temperatures of -30°C because of the auto heat-up function. Another element that makes it more powerful is the smart and dynamic adjustment of CPU and GPU when the processors are at heavy workloads. This becomes very important to keep the hardware safe from overheating, making it more stable for critical applications.

DFI's desktop motherboard is built for edge applications that work in extreme weather conditions and require a small form factor that provides more AI capabilities. As per requirement, this DFI's CS551 3.5" SBC seems to be a perfect fit that gives high performance with a small footprint. Along with this, the CS551 is integrated with DDR4 RAM supporting up to 2666MHz 32GB high-speed read/write for image analysis performance.

"Unlike other 3.5” SBCs on the market that only support M.2 2242 expansion, the CS551 increases the expansion capacity up to M.2 2280 size, making it perfectly compatible with M.2 2280 form factor-only modules, as well as providing more than two times of the storage capacity and I/O expansion," DFI notes.

With the upgraded expansion capabilities, the desktop SBC gives the user to add more storage and IO interfaces. However, the greater focus from the manufacturer is extreme weather performance. With the dual cooling system (fan/fanless), the motherboard can work at 80°C, which does not happen in normal desktops.
