H0 Smart HMI Mainboard Allwinner A40i quad-core Cortex-A7 @1.2GHz Android 7.1

H0 Smart HMI Motherboard

Overview

The H0 Smart HMI Motherboard is a versatile and cost-effective platform designed for human-machine interface (HMI) applications across industrial automation, smart home, medical devices, and commercial equipment. Powered by the Allwinner A40i quad-core Cortex-A7 processor running at up to 1.2GHz, with Mali-400MP2 GPU supporting OpenGL ES 2.0 and 1080P hardware video decoding, the H0 delivers reliable performance for GUI applications. The board features three display interfaces — LVDS (dual-channel, up to 1080P), HDMI 1.4 (up to 1080P), and MIPI-DSI — offering flexible panel connectivity for various HMI designs. Comprehensive I/O includes 7× serial ports (1 TTL/RS-485 + 6 TTL/RS-232), 9× USB 2.0 ports (2 external + 7 internal), 5× GPIO, I2C, and 10/100M Ethernet. The H0 also features 8Ω 6W dual amplifier output, CTIA 4-pole headset jack, differential MIC input, and wide-temperature operation from -20°C to 70°C. With Android 7.1 support, open API SDK, and the most serial ports in the HMI lineup, the H0 is the ideal foundation for custom HMI development.

Key Advantages

• Triple Display Interface Flexibility: LVDS, HDMI 1.4, and MIPI-DSI support a wide range of display panels — from cost-effective industrial screens to consumer-grade HDMI monitors — adapt to different project requirements without hardware redesign.

• Industry-Leading Serial Connectivity: 7× configurable serial ports (1 TTL/RS-485 + 6 TTL/RS-232) provide exceptional connectivity for legacy industrial equipment, sensors, barcode scanners, and controllers — more than any other board in its class.

• 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), 5× GPIO, I2C for capacitive touch, and backlight control — all the connectivity needed for complete HMI solutions.

• Wide-Temperature Reliability: -20°C to 70°C operating temperature range ensures stable operation in industrial environments, outdoor kiosks, and cold chain applications.

• Cost-Optimized Android Platform: Android 7.1 with open API SDK enables rapid application development while keeping BOM costs competitive — ideal for volume HMI deployments.

Why Choose This Board?

• Most Serial Ports in the HMI Lineup: With 7× configurable serial ports, the H0 connects to more industrial peripherals than competing boards — perfect for applications requiring multiple device connections like barcode scanners, printers, PLCs, and sensors.

• Three Display Interfaces, One Board: LVDS for industrial panels, HDMI for consumer displays, and MIPI-DSI for flexible FPC connections — choose the display technology that fits your design without compromising on board compatibility.

• Complete Audio Solution: 8Ω 6W amplifier + CTIA headset jack + differential MIC input — handle speaker output, headset communication, and microphone input with a single board.

• Industrial-Ready, Cost-Effective: -20°C to 70°C operating range and robust I/O make the H0 suitable for demanding environments, while the A40i platform keeps costs competitive for high-volume HMI projects.

• Open for Custom Development: Android 7.1 with open API SDK enables fast application development, UI customization, and integration with existing systems — get your HMI product to market faster.
