Overview
The ELSKY QM9850 is industrial-grade Mini-ITX motherboards designed for 24/7 continuous operation. Based on the Intel chipset, these boards support Intel 8th Generation Core processors (including i5-8250U, i7-8550U, etc.), delivering powerful performance for embedded and industrial applications.
Features
High-Speed Memory Support: Equipped with 2 x NB-DDR4 memory slots, the motherboard supports up to 64GB of 2133/2400MHz memory. This enables fast data access and processing, enhancing overall system performance for memory-intensive applications such as data analysis and multitasking.
Triple 4K Display Output: Featuring HDMI 1.4 (4K@30Hz), DP 1.4 (4K@60Hz), VGA, LVDS, and eDP interfaces, the motherboard supports triple independent 4K displays. This makes it ideal for digital signage, medical equipment, and multi-screen industrial workstations.
Flexible Network Options: With 1 or 2 x Realtek 8111H Gigabit LAN ports, the motherboard supports network wake-up and PXE functionality. Dual LAN configuration provides redundancy and enhanced network security for critical applications.
High-Speed Storage Support: The motherboard includes 1 x M.2 2280 NVMe/SATA adaptive SSD slot and 1 x SATA 3.0 port. The M.2 slot supports PCIe 3.0 x4 for ultra-fast data transfer, significantly accelerating system boot and software loading.
Application
Industrial Control Systems: Ideal for factory automation, CNC machines, and PLC systems. Supports 6 x COM ports, -10°C to 60°C operation, and watchdog timer for reliable 24/7 performance.
Digital Signage: Triple independent 4K display output (HDMI, DP, VGA, LVDS, eDP) makes it perfect for multi-screen signage in retail stores, airports, and hotels.
Self-Service Kiosks: Compact Mini-ITX (170x170mm) fits easily into kiosks, ATMs, and interactive terminals. Rich I/O including USB, COM, and dual LAN options ensure reliable connectivity.
Embedded Automation: Flexible storage (M.2 NVMe + SATA 3.0) and Mini-PCIe for WiFi/4G modules make it suitable for smart manufacturing, IoT gateways, and environmental monitoring.
