: Some configurations use this PCB with an LGA1150/1155 socket, supporting Intel Core i5 processors (e.g., i5-4440S) for automated machinery like library sorting machines.
: The standard UL 94 vertical burn safety rating for safety compliance.
: A standard UL (Underwriters Laboratories) flammability rating for the plastics and materials used in the board. E89382 : The UL certification number for HannStar. 2. Common Hardware Variants
HannStar K MV-4 94V-0 is a specific type of printed circuit board (PCB) manufactured by HannStar Display Corp. It is important to note that "MV-4 94V-0" refers to the board's material rating and safety standards hannstar k mv-4 94v-0 motherboard
Verify the onboard CPU and GPU configuration (some models come with integrated Intel graphics, while others feature dedicated NVIDIA or AMD chips).
In the consumer PC industry, motherboards are marketed with flashy heatsinks, RGB lighting, and chipset names. However, the vast majority of printed circuit boards (PCBs) that run our world are utilitarian, anonymous, and designed for a single purpose. The board labeled "Hannstar MV-4 94V-0" is a perfect artifact of this hidden ecosystem. Far from being a high-performance gaming board, the MV-4 represents a class of durable, cost-effective, and highly specific electronics designed for longevity in industrial or arcade environments.

You will frequently find this marking inside multi-processor servers from major vendors. These designs feature heavy-duty supporting quad-CPU configurations, or integrated Intel Xeon processors running low-power enterprise network loops. They often serve as storage array controllers or routing management sub-boards. 3. Machine Control Modules & PLCs

If you are holding a Hannstar K MV-4, it likely came from one of these pre-built computers:
HannStar K MV-4 94V-0 is an industrial-grade motherboard primarily utilized in specialized environments such as industrial automation, manufacturing control systems, and digital signage. Unlike consumer-facing motherboards, the K MV-4 is designed for long-term stability and durability in harsh conditions. Core Technical Profile The board is manufactured by HannStar Board Corporation
: Check for "cracked solder joints," a common issue on older HannStar PCBs. Some users have successfully revived these boards by reflowing (reheating) specific areas, though this is a high-risk temporary fix.
: This is a specific raw board laminate material designation. It informs technicians that the underlying glass-reinforced epoxy (FR-4) meets exact thermal, layer count, and electrical insulation profiles.
Repairing a machine via a Radwell 2-year warranty-backed component is far cheaper than replacing the entire industrial machine. Applications of the K MV-4 94V-0 The HannStar K MV-4 94V-0 is frequently found in:
