K-A311D Smart IoT Motherboard with 5T computing power 4GB of RAM and 128GB of storage

K-A311D Smart IoT Motherboard

Overview

     The K-A311D Smart IoT Motherboard is the flagship of the K-series, engineered for the most demanding AI-powered IoT applications. Powered by the Amlogic A311D hexa-core processor (quad Cortex-A73 @ 2.2GHz + dual Cortex-A53) with a built-in 5 TOPS NPU — the highest AI acceleration in the lineup — this board delivers desktop-class performance for real-time object detection, facial recognition, and complex neural networks. What sets the K-A311D apart is its MIPI-CSI camera interface for superior image capture, 6× configurable serial ports, USB 3.0, Gigabit Ethernet with PoE, and wide-temperature operation from -20°C to 70°C. With support for up to 4GB LPDDR4 memory and Android 9.0, the K-A311D is purpose-built for AI-powered vending machines, smart interactive systems, and advanced industrial control applications where performance and AI capability are non-negotiable.

Key Advantages

• 5 TOPS NPU — Highest AI Acceleration in K-Series: 5× more powerful than the K-3566's 1 TOPS NPU — run multiple AI models simultaneously, process high-resolution video streams, and handle complex neural networks with ease, all on-device without cloud dependency.

• 2.2GHz Cortex-A73 Cores — Desktop-Class Performance: The quad Cortex-A73 cores deliver significantly higher single-core performance than Cortex-A55 or Cortex-A53 — faster AI inference, smoother UI, and better multitasking for the most demanding applications.

• MIPI-CSI Camera Interface: Dedicated 24-pin MIPI-CSI input delivers superior image quality and lower latency than USB cameras — essential for AI-powered visual applications where every frame matters.

• 6× Configurable Serial Ports: 1× TTL/RS-485, 2× TTL/RS-232, and 4× extended TTL/RS-232 — flexible connectivity for payment systems, sensors, and industrial controllers.

• PoE-Ready Gigabit Ethernet: 10/100/1000M Ethernet with PoE support — fast networking and simplified cabling for retail and industrial deployments.

Why Choose This Board?

• Built for AI Workloads, Not Just Specs: The 5 TOPS NPU paired with 2.2GHz Cortex-A73 cores means the K-A311D handles complex AI models that other boards can't — real-time object detection, multi-person tracking, and video analytics all run simultaneously without bottleneck.

• MIPI-CSI — Capture Quality That USB Can't Match: USB cameras are convenient, but MIPI-CSI delivers higher resolution, lower latency, and better synchronization — the difference between a system that occasionally misidentifies products and one that's accurate every time.

• The Board That Grows With Your AI Needs: As AI models become more complex, the K-A311D's 5 TOPS NPU ensures your hardware keeps up. Invest in the board that won't be obsolete in two years when the next generation of AI models demands more compute.

• Power Through Complex Applications: From AI-powered vending machines that recognize products in real-time to interactive kiosks with live video analytics — the K-A311D delivers the processing power and camera connectivity that entry-level boards simply cannot provide.
