Product Specification

H-3399 Smart HMI Motherboard

Overview

     The H-3399 Smart HMI Motherboard delivers flagship performance for demanding human-machine interface applications, powered by the Rockchip RK3399 hexa-core processor (dual Cortex-A72 @ 1.8GHz + quad Cortex-A53 @ 1.4GHz). This big.LITTLE architecture provides exceptional computing power for AI-driven applications, making it ideal for service robots, face detection and recognition systems, industrial control equipment, and interactive kiosks. The Mali-T860 GPU supports 4K hardware decoding via HDMI 2.0a, while the board offers four display interfaces — LVDS (1080P), HDMI 2.0a (4K), MIPI-DSI, and eDP (1080P) — providing unmatched display flexibility. With USB 3.0 ports, Gigabit Ethernet, 8Ω 6W dual amplifier output, CTIA 4-pole headset jack, differential MIC input, and support for Android 7.1/8.1/9.0 and Linux (Buildroot/Debian 9/Ubuntu 18.04), the H-3399 is the ultimate platform for advanced HMI and edge intelligence applications.

Key Advantages

• Hexa-Core big.LITTLE Architecture: The RK3399's dual Cortex-A72 cores handle intensive AI inference and multimedia processing while quad Cortex-A53 cores manage background tasks — delivering desktop-class performance with excellent power efficiency.

• Four Display Interfaces for Ultimate Flexibility: LVDS + HDMI 2.0a (4K) + MIPI-DSI + eDP — support virtually any display technology, from industrial panels to 4K monitors, without hardware redesign.

• USB 3.0 + Gigabit Ethernet: USB 3.0 delivers 10× faster data transfer than USB 2.0 for high-speed camera uploads and firmware updates, while Gigabit Ethernet ensures fast, reliable network connectivity for cloud-based services and remote management.

• Multi-OS Support: Android 7.1/8.1/9.0 and Linux (Buildroot/Debian 9/Ubuntu 18.04) — choose the platform that best fits your application, from Android apps to custom Linux development.

• Built-in Audio Amplifier: 8Ω 6W dual amplifier drives speakers directly — no external amplifier board needed for voice prompts, alarm notifications, or audio feedback.

• 5MP Camera Support: Supports USB cameras up to 5MP — high-resolution image capture for face recognition and visual inspection applications.

Why Choose This Board?

• AI-Ready Processing Power: The RK3399 provides the compute headroom needed for on-device AI inference — run face detection, object recognition, and machine learning models directly on the board. No cloud latency, no external NPU required (though expansion is available).

• Most Display Interfaces in the HMI Lineup: With LVDS, HDMI 2.0a (4K), MIPI-DSI, and eDP, the H-3399 offers unmatched display flexibility — adapt to any panel technology without board changes.

• Built for Robotics and Intelligent Systems: Service robots, face recognition terminals, and industrial controllers demand both processing power and connectivity. The H-3399 delivers with hexa-core performance, USB 3.0, Gigabit Ethernet, and flexible OS options.

• Enterprise-Grade Connectivity: USB 3.0 and Gigabit Ethernet provide the high-speed data transfer essential for AI applications — fast camera uploads, real-time cloud communication, and large data transfers.

• Operating System Freedom: Whether you're building on Android or Linux, the H-3399 supports both — choose the platform that fits your development team's expertise and application requirements.
