Qtenboard MG520.U Mainboard for High-end Conference Interactive All-in-One Devices

  Qtenboard MG520.U is a premium core mainboard specially engineered for high-end conference Interactive flat panel devices, tailored to meet the demands of modern business meetings and smart office scenarios. Built upon the mature MTK G520 solution, this mainboard has undergone two rounds of iterative optimization, delivering outstanding performance, remarkable stability and versatile expandability. Fully tested and polished for long-term operation, it serves as an ideal core component for large-size interactive conference terminals, striking a perfect balance between daily office practicality and functional expandability, and standing out among mainstream mainboards for conference equipment.

  Powerful hardware configurations lay a solid foundation for exceptional computing performance. The mainboard is equipped with an octa-core processor consisting of 2 ARM Cortex-A78 cores and 6 ARM Cortex-A55 cores, paired with a Mali-G57 MC2 graphics chip to ensure stable operating frequency and outstanding audio and video processing capabilities. It adopts flexible memory and flash storage configurations. The standard DDR4 memory is 8GB, expandable up to 16GB, while the default eMMC flash storage is 128GB with a maximum capacity of 512GB. Such specifications easily support multi-task background operation and massive storage of meeting documents, videos and presentation files. In terms of software, it runs on deeply customized Android 16.0 with a 6.1 kernel, delivering ultra-smooth system operation. It supports 4K@60Hz dual-screen simultaneous display and hardware decoding for 4K@60fps high-definition videos, presenting crisp and fluent visual effects for courseware playback, video conferencing and multimedia demonstrations.

  One of the core strengths of Qtenboard MG520.U lies in its comprehensive port matrix and flexible optional functions. It integrates a full range of audio, video, network and control interfaces, including RS232 serial port, optical fiber output, line output, analog microphone port, dual RJ45 network ports, TF card slot, multiple USB ports, HDMI, DP and VGA interfaces, covering all connection requirements of professional conference equipment. Users can select different Wi-Fi and Bluetooth modules as needed, including mainstream Wi-Fi 6 and Wi-Fi 7 solutions. Additionally, the mainboard allows connections to various external peripherals, such as 8-channel array microphones, NFC modules, ambient light sensors and human body induction sensors, enabling advanced features like intelligent sound pickup, human body detection and identity recognition. Its built-in audio system supports 2.0 or 2.2-channel speakers and subwoofers with steady output power, guaranteeing clear sound collection and audio playback in meeting rooms.

  Strict electrical design and excellent environmental adaptability ensure reliable long-term operation. The mainboard supports multi-channel power supply of 5V, 12V and 18V with reasonable voltage fluctuation range, and its standby power consumption is lower than 0.3W, which is energy-efficient and safe. Clear regulations on power-on sequence and current limits of USB ports effectively prevent equipment failures caused by overloaded external devices. For environmental adaptation, it works stably at temperatures from 0℃ to 40℃, and can be stored safely in environments ranging from -20℃ to 85℃. Both operating and storage humidity comply with non-condensation standards, making it adaptable to diverse office environments across different regions. As an electrostatic-sensitive device, it has clear guidelines for installation, wiring and cable selection to avoid damage from bending or extrusion. Users are also reminded to complete relevant patent authorizations for audio and video formats and interface technologies before official use.

  Overall, Qtenboard MG520.U features balanced performance, complete functions and reliable quality. It is a high-performance mainboard that fully caters to the application needs of high-end conference Interactive flat panel devices, earning strong competitiveness in the smart office hardware market.
