What is its core positioning? A: The PCM-S351 is a standard 3.5-inch form factor wide-temperature industrial motherboard developed by YDS TECH. Its core positioning is to provide high-performance, low-power and highly reliable computing cores for embedded and compact industrial equipment. Equipped with Intel's mature low-power processor platform and native fanless design, it perfectly adapts to space-constrained and harsh industrial environments, solving the common pain points of traditional consumer motherboards such as easy failure under vibration, dust and extreme temperature conditions.Q3: Which processors does this embedded mainboard support? What performance requirements can it meet? A: The PCM-S351 is fully compatible with Intel 6th Generation Skylake-U and 7th Generation Kaby Lake-U series low-power processors, with a unified TDP of 15W, covering entry-level to mid-to-high-end computing needs. Supported models include Core i3-6100U/7100U/7020U, i5-6200U/7200U, i7-6500U/7500U and other mainstream industrial processors. Its performance is more than sufficient to support most industrial scenarios, including industrial control, data acquisition, lightweight edge computing, machine vision inspection and human-machine interfaces (HMI). Unlike consumer-grade motherboards, it has no peak power fluctuations, ensuring stable 24/7 operation in industrial environments.Q4: What are the characteristics of the memory and storage configuration? Are they suitable for industrial environments? A: To address the problem of hardware loosening caused by strong vibration in industrial sites, the PCM-S351 industrial motherboard adopts an on-board DDR4 memory design, offering three capacity options: 4GB, 8GB and 16GB. It operates at a low voltage of 1.2V with a maximum frequency of 2133MHz, completely eliminating equipment downtime caused by loose memory slots. In terms of storage, it is equipped with 2 SATA 3.0 standard interfaces + 1 mSATA 3.0 interface, supporting hybrid deployment of mechanical hard drives (HDD) and solid-state drives (SSD). This configuration can meet both large-capacity data storage needs and high-speed system boot and read/write requirements.Q5: Is the interface configuration rich? Which industrial peripherals can it be compatible with? A: The PCM-S351 embedded mainboard features a full set of industrial-grade interfaces, allowing connection to most industrial equipment without additional expansion cards:

• Display: 1 VGA + 1 HDMI + 1 18/24-bit single/dual-channel LVDS, supporting three independent 1080P@60Hz displays

• Network: Dual Intel Gigabit Ethernet (I219V/LM + I211AT/I210AT), supporting network redundancy and load balancing

• Serial Ports: 6 RS232 (3-wire) ports, among which COM1 and COM2 support optional RS232/RS422/RS485 protocols

• USB: 4 front USB 3.0/2.0 + 4 internal USB 2.0, balancing external device connection and internal expansion

• Expansion: 1 mPCIe slot, 1 optional SIM card slot, 8 front GPIO (General Purpose Input/Output) interfaces

• Audio: ALC662 high-fidelity audio codec, supporting Line-in, Line-out and Mic-in

Q6: How is the environmental tolerance of this industrial motherboard? Can it operate in extreme temperatures? A: The PCM-S351 is specifically designed for harsh industrial environments and has exceptional environmental adaptability:

• Standard version operating temperature: -20°C to +60°C

• Optional industrial-grade wide-temperature version: -40°C to +75°C It can cover extreme temperature scenarios such as cold outdoor environments in northern regions, high-temperature workshops in southern areas, and on-board equipment, ensuring uninterrupted operation of equipment throughout the year. In addition, it uses industrial-grade components and has excellent vibration and shock resistance.

Q7: Why adopt a fanless design? What advantages does it have over motherboards with fans? A: The PCM-S351 embedded mainboard natively adopts a fanless passive cooling design (fan is optional), which is one of the core advantages of industrial-grade motherboards:

1. No mechanical moving parts, completely eliminating equipment overheating and downtime caused by fan failure

2. Fully sealed heat dissipation structure, effectively blocking dust and moisture from entering the motherboard, extending service life

3. Silent operation, suitable for noise-sensitive scenarios such as medical equipment and laboratories

4. Significantly increases the Mean Time Between Failures (MTBF) of equipment, reducing later maintenance costs

Q8: Which operating systems and wireless expansion functions are supported? A: In terms of operating systems, it is fully compatible with Windows 7, Windows 10 and Linux, the three mainstream industrial operating systems. It adapts to most software and driver ecosystems in the industrial field, enabling rapid deployment without additional adaptation work. For wireless expansion, it supports 4G full-network wireless communication through the mPCIe slot combined with the optional SIM card slot, meeting the needs of remote data transmission, remote monitoring and operation and maintenance for IoT devices.Q9: In which industries and equipment is the PCM-S351 mainly used? A: With its comprehensive functions and high reliability, the PCM-S351 industrial motherboard has been widely used in the following fields:

• Medical Equipment: Ultrasound diagnostic instruments, patient monitors, clinical analyzers, medical imaging equipment
