⚠️ Important Notes
Memory Specifications: Supports DDR3L SO-DIMM memory modules only (1.35V low voltage). Standard DDR3 (1.5V) modules are not compatible. Maximum supported capacity is 8GB.
Extended Temperature Operation: This motherboard supports operation down to -20°C, making it suitable for cold storage, outdoor, and extreme environment applications. Ensure proper thermal design for reliable operation at temperature extremes.
Power Supply Requirements: Use a stable, high-quality DC 12V ±5% power adapter with adequate current capacity. When utilizing all 9 USB ports, multiple serial devices, and expansion modules, ensure the power supply can deliver sufficient current (typically 4-6A recommended).
Serial Port Configuration: The board provides 6 RS232 serial ports with support for 4 RS485 interfaces. RS485 functionality is configurable from specific RS232 ports. Verify port assignments and configuration requirements for your application.
Display Connectivity: The VGA interface is provided as a header connector requiring appropriate cabling to external connector. LVDS interface supports optional eDP displays – specify display requirements when ordering.
Network Configuration: Standard configuration includes dual Gigabit Ethernet ports. Optional single network port configuration is available for applications requiring only one network connection.
Clear CMOS Function: The dedicated Clear CMOS button allows easy BIOS reset without opening the enclosure. This is particularly useful in sealed systems where physical access to jumpers is limited.
