In Qtenboard's 2025–2026 mainboard portfolio, the 311D2 is positioned as the mid-range volume workhorse — below the AI-powered 3576 and 9679 flagship platforms. It is a mature, proven platform built on the Amlogic A311D2 octa-core SoC, designed specifically for OEM/ODM partners, system integrators, and tender-focused customers who need rock-solid stability, broad compatibility, and aggressive cost-efficiency for large-scale education, government, and enterprise deployments.
The 311D2 is powered by the Amlogic A311D2 octa-core processor, featuring four Cortex-A73 cores clocked at up to 2.2GHz and four Cortex-A53 cores at up to 2.0GHz. This big.LITTLE architecture delivers responsive UI performance, smooth 4K decoding, and efficient power management — making it ideal for interactive flat panels in classrooms, meeting rooms, and digital signage networks. The chip also integrates a 3.2 TOPS NPU for basic on-device AI workloads.
Octa-core A73×4 @ 2.2GHz + A53×4 @ 2.0GHzThe Mali-G52 MP8 (8EE) GPU delivers sustained 4K @ 60Hz multi-stream hard decoding. Whether powering an 86-inch interactive flat panel in a school or a digital signage wall in a shopping mall, the 311D2 ensures crisp video playback, smooth UI transitions, and zero frame drops — even during extended daily operation. It also supports 8K AV1 decoding at 24fps.
4K @ 60Hz | Mali-G52 MP8 GPU | 8K AV1 DecodeThe 311D2 features a versatile V-by-One signal bus that seamlessly drives panels from 55" up to 110". It supports plug-and-play integration with 10, 20, or 40-point IR touch arrays and PCAP touch sensors. Standard OPS slot enables instant Android + Windows dual-system switching. The platform also supports up to 16GB LPDDR4/X memory and flexible storage configurations.
55"–110" | 40-Point Touch | OPS ReadyThe 311D2 runs on a refined Android 14 environment with Google EDLA certification, enabling full access to Google Mobile Services, Google Play, and the Google Classroom ecosystem. Qtenboard provides dedicated long-term firmware maintenance to ensure platform stability across multi-year project rollouts.
Android 14 | Google EDLA | Long-Term SupportThe 311D2 is a mature platform that has been extensively validated in real-world deployments across education, government, and enterprise sectors. Built on the Amlogic A311D2 chipset, it has reached a stage of exceptional stability and reliability. However, it is important to note that no major performance iterations or generational upgrades are planned for this platform. The 311D2 is what it is — a stable, reliable, and cost-effective workhorse. For partners who need cutting-edge AI capabilities, independent NPUs, or next-gen Android versions, Qtenboard recommends the 3576 or 9679 platforms. But for high-volume education tenders, government contracts, and cost-sensitive commercial projects where proven reliability matters more than peak specs, the 311D2 remains an outstanding choice. The A311D2 chip alone shipped over one million units in 2024 and is expected to exceed another million in 2025, underscoring its widespread adoption and proven track record in the commercial display market.
The 311D2 is purpose-built for specific deployment scenarios where cost-efficiency, stability, and proven reliability outweigh cutting-edge AI features or peak performance numbers. It is the go-to mid-range choice for buyers managing large-scale, budget-conscious projects.
Large-scale public education projects demand hardware that minimizes maintenance overhead and withstands daily classroom use. The 311D2's balanced thermal design and low failure rate make it a preferred choice for ministry-level tenders.
Small-to-mid-size businesses need affordable, reliable collaboration tools. The 311D2 delivers smooth 4K video conferencing, wireless screen sharing, and low-latency annotation at a competitive price point.
Shopping malls, airports, and retail chains run digital signage around the clock. The 311D2 handles complex multimedia playback and real-time content rotation without crashing or frame drops.
Southeast Asia, the Middle East, Latin America, and Africa represent fast-growing markets where cost optimization is critical. The 311D2 enables international brands to execute massive interactive deployments at competitive price points.
Self-service information kiosks in government buildings, transit hubs, and public spaces require reliable 24/7 operation. The 311D2's industrial-grade stability ensures uninterrupted service.
NGOs rolling out digital classrooms in developing regions need hardware that is durable, easy to maintain, and cost-effective. The 311D2's proven reliability and long-term firmware support make it an ideal choice.
The 311D2 is not just a mainboard — it is a platform that global distributors, system integrators, and OEM/ODM partners can adapt to their specific market needs without re-engineering hardware from scratch.
Qtenboard provides comprehensive white-label services for the 311D2 platform, enabling partners to launch branded interactive display products with minimal development overhead. From boot animations to system-level UI, every aspect can be tailored to your market positioning.
