H3 Smart HMI Motherboard

Overview

The H3 Smart HMI Motherboard elevates human-machine interface performance with the Rockchip RK3288 quad-core Cortex-A17 processor running at 1.8GHz, delivering significantly faster application response and smoother UI transitions than entry-level HMI boards. The Mali-T764 GPU supports OpenGL ES 1.1/2.0/3.1 and provides 4K hardware video decoding — enabling stunning ultra-HD display output for premium HMI applications. The board features three display interfaces (LVDS up to 1080P, HDMI 2.0 up to 4K, and MIPI-DSI), 8Ω 6W dual amplifier output, CTIA 4-pole headset jack, differential MIC input, and 4× TTL/RS-232 serial ports. With 9× USB ports (2 external + 7 internal), 5× GPIO, I2C, 10/100M Ethernet, wide voltage input, and support for Android 5.1 through 8.1, the H3 delivers the performance and flexibility needed for advanced HMI applications in industrial automation, medical devices, smart retail, and commercial equipment.

Key Advantages

• 4K Display for Premium HMI: HDMI 2.0 output with 4K resolution support enables stunning ultra-HD interfaces — perfect for medical imaging displays, high-end industrial control panels, and premium retail kiosks where visual quality matters.

• 1.8GHz Processing Power: The RK3288's 1.8GHz clock speed delivers noticeably faster UI responsiveness and application performance than entry-level HMI boards — smoother animations, quicker screen transitions, and better multitasking.

• Triple Display Interface Flexibility: LVDS, HDMI 2.0, and MIPI-DSI support a wide range of display panels — from cost-effective industrial screens to 4K consumer monitors — adapt to different project requirements without hardware redesign.

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

• Flexible I/O and Expansion: 9× USB ports (2 external + 7 internal), 4× serial ports, 5× GPIO, I2C for capacitive touch, and backlight control — all the connectivity needed for complete HMI solutions.

• Multi-OS Flexibility: Supports Android 5.1, 6.0, 7.1, and 8.1 — choose the version that best fits your application requirements and testing/certification needs.

Why Choose This Board?

• 4K Visuals for Premium HMI: 4K display support sets the H3 apart from standard 1080P HMI boards — deliver stunning ultra-HD interfaces for medical displays, control room dashboards, and high-end industrial panels where image clarity is critical.

• Noticeably Smoother UI Experience: At 1.8GHz, the RK3288 delivers significantly faster UI responsiveness than entry-level HMI platforms — smoother animations, instant touch response, and better overall user experience.

• Broad Android Version Support: From Android 5.1 to 8.1, the H3 offers the widest OS version flexibility in the HMI lineup — accommodate legacy application compatibility requirements or future-proof with newer versions.

• Complete Display Ecosystem: LVDS for industrial panels, HDMI 2.0 for 4K monitors, and MIPI-DSI for flexible FPC connections — choose the display technology that fits your design without board changes.

• Open for Custom Development: Open API SDK with Android support enables fast application development, UI customization, and integration with existing systems — get your HMI product to market faster.
