Our embedded mainboard and industrial motherboard power applications across Artificial Intelligence, Edge Computing, Intelligent Transportation System (ITS), Electric Vehicle Charging Pile (EVCP), Smart Grid, Machine Vision, Numerical Control System, Robotics, Face Recognition and Internet of Things.

Q1: What is PCM-E351? What form factor does this embedded mainboard adopt? A: PCM-E351 is a 3.5-inch motherboard sized at 146mm × 102mm. It is an x86 embedded mainboard, also widely known as industrial motherboard, industrial computer motherboard and industrial automation motherboard. Built with Intel Elkhart Lake series SOC and fanless passive cooling architecture, this wide-temperature industrial motherboard is optimized for seamless integration into all kinds of embedded industrial devices.

Q2: How about the thermal performance of this wide-temperature industrial motherboard? Can it withstand extreme hot and cold working conditions? A: The standard model runs reliably from -20℃ to +60℃. Our premium wide-temperature variant supports stable operation between -40℃ and +75℃, making it one of the most robust options for outdoor deployments, sealed hot cabinets and low-temperature field environments. The fanless design eliminates moving mechanical parts, delivers ultra-low failure rates and supports 7/24 non-stop long-run operation.

Q3: What I/O interfaces and expansion options are available on this industrial motherboard? A: ▪ Display: VGA, HDMI, eDP, LVDS, multi-channel independent display output ▪ Network: Dual Gigabit RTL8111H Ethernet ports ▪ Serial: 6 × RS232; COM1 & COM2 support RS232 / 422 / 485 switch ▪ USB: 4 × USB3.0 + 4 × USB2.0 ▪ Storage: SATA3.0, M.2 M-Key slot; M.2 E-Key for Wi-Fi, M.2 B-Key for 4G LTE module ▪ Extra: 8-ch GPIO, audio codec, SIM card holder ▪ Memory: SO-DIMM DDR4 socket, up to 16GB ▪ Power: Wide voltage input +12V ~ +24V ▪ OS Compatibility: Windows 10, Windows 11, Linux

Q4: What projects can this embedded mainboard support? A: This versatile industrial motherboard serves as intelligent transportation motherboard for ITS roadside edge terminals and traffic control hardware; EV charging motherboard for electric vehicle charging control units; smart grid motherboard for power data acquisition and substation monitoring terminals; machine vision motherboard for image capture and inspection equipment; numerical control system motherboard for CNC controllers; robotics motherboard for industrial and mobile robot controllers; face recognition motherboard for biometric detection terminals; IoT motherboard for IoT gateways and edge data collectors. It also works perfectly as medical equipment motherboard for medical inspection and monitoring terminals, plus all AI, edge computing and industrial automation embedded systems. The rich I/O set easily connects to a huge range of peripheral hardware.

Q5: What is the difference between consumer PC mainboards and embedded mainboard? Why do industrial projects prefer industrial automation motherboard? A: Consumer motherboards are designed only for indoor ambient temperature and intermittent use. Industrial motherboard and wide-temperature embedded mainboard are engineered specifically for harsh industrial sites. They feature wide temperature tolerance, wide voltage input, dedicated industrial serial and GPIO interfaces, and long product lifecycle supply. They are built for 7/24 continuous operation with minimal downtime and remarkably low failure rates, cutting maintenance costs dramatically. For outdoor, high-temperature cabinet and cold-site installations, the rugged hardware from a professional 3.5-inch industrial motherboard supplier delivers far superior stability compared with consumer-grade alternatives.

Q6: As a leading wide-temperature industrial computer manufacturer and embedded solution provider, what services can YDS TECH offer? Do you support custom development? A: YDS TECH is a trusted x86 industrial computer manufacturer and embedded computing solution house. Beyond standard stock PCM-E351 embedded mainboard, we offer full OEM and ODM customization, including interface reconfiguration, wide-temperature upgrade, BIOS tuning and complete embedded system turnkey solutions. We provide sample testing, mass production supply and dedicated technical support for AI, edge computing, ITS, EV charging, smart grid, machine vision, CNC, robotics, face recognition and IoT customers worldwide.

Q7: How can I confirm whether PCM-E351 embedded mainboard fits my project? A: Prepare your core requirements including operating temperature range, required Ethernet / COM / USB quantity, storage scheme, operating system and enclosure mounting dimension, then reach out to our engineering team for a detailed evaluation. Multiple Elkhart Lake CPU options including N6210, J6412, N6415 and Atom X series are available, so you can select the perfect processor matching your computing demand.
