Technical Specifications: How Our Dashboards Perform

An in-depth breakdown of sensor configurations, wireless protocols, and rugged design engineering.

Multifunctional Dashboard Racing Systems

Advanced Signal Interpretation and High Ingress Protection

Our premium telemetry models, such as the DO908 Waterproof Series, are built using specialized outdoor-viewable displays and ruggedized housings. Unlike generic tablets or modified consumer displays, our race dashboards are engineered to withstand continuous engine vibrations, extreme sunlight glare, and intense thermal fluctuations.

  • Dual Interface Connectivity: Select dashboards feature both OBD-II direct integration for late-model engines and specialized sensor distributor bundles. Drivers can read ECU data streams while simultaneously monitoring dedicated analog oil temperature, fuel level, and boost pressure inputs.
  • Wireless Sensor Transmission: Our 9-in-1 Bluetooth sensor kits utilize high-frequency, low-interference wireless channels to transmit engine sensor data directly to the dashboard, simplifying firewall routing and minimizing chassis wiring clutter.
  • Ingress Protection: Waterproof dashboard models feature silicon-sealed enclosures (IP65-IP67 equivalent), protecting critical LCD/OLED drivers and internal circuit components from heavy rain, splash, and dust during open-cockpit rally, boat racing, or off-road conditions.
  • Universal Voltage Integration: Intelligent power regulator modules support clean operation under 12V and 24V vehicle battery systems, protecting dashboard circuits from power spikes, reverse polarities, and high-frequency alternator noise.

Global Compliance and Localization Support

International B2B distribution requires strict adherence to regional safety and electronics compliance certifications. Because our products are distributed to Europe, North America, Australia, and Asia, DongOu implements comprehensive quality certifications.

Compliance Checkpoints: CE, RoHS, & FCC Standards

We ensure that our race dashboards comply with the European Union's RoHS directive, preventing the use of hazardous substances in our SMT solder and plastic housings. Internal circuit boards are shielded to block electromagnetic interference (EMI), satisfying both FCC Part 15 and CE standards.

For localization, our dashboards include switchable unit systems. Drivers can toggle between Imperial (Fahrenheit, PSI, MPH) and Metric (Celsius, Bar, KM/H) readouts. Furthermore, our screen firmware supports variable warning threshold presets. Installers can easily calibrate warnings for low oil pressure, high water temperature, or excessive boost, which trigger warning LEDs instantly. These configurations make our gauges suitable for global performance shops, engine tuners, and vehicle fleet managers.

Auto Instrument Calibration Equipment

Practical Application Scenarios & Environments

From amateur rally configurations to professional closed-circuit racing and marine operations.

Professional Motorsports

Track cars and time-attack builds utilize our high-brightness LCD dashboards to compile oil pressure, tachometer RPM bands, and critical engine temperatures into a single, high-contrast display panel.

Extreme Rally & Marine

Off-road rally racing and marine environments subject gauges to water spray and dust. Our waterproof DO908 dashboard prevents dust ingress and handles moisture exposure during rugged environments.

Modified & Customized Vehicles

Custom car collectors and modification shops use the 2-inch and 60mm GragonGauge instrumentation sets to maintain retro layouts while securing modern sensor response speeds and reliability.

B2B Sourcing FAQ: Key Purchasing Questions

Information gain for procurement officers regarding protocols, manufacturing capabilities, and order customization.

Q1: Can your digital dashboards connect directly to aftermarket ECUs via CAN bus?

A: Yes. High-end SincoTech dashboards, such as the DO926 and DO908 series, support standard OBD-II protocols and can be integrated with various aftermarket ECU protocols. For custom CAN bus map configurations, our R&D department can adjust firmware configurations to decode your specific ECU communication matrix.

Q2: What is the Minimum Order Quantity (MOQ) for custom private labeling?

A: For direct OEM/ODM customization—including custom startup screens, brand logos printed on the dashboard frame, or specific sensor kit lengths—our MOQ starts at 50 units. Standard, unbranded orders or wholesale distributor packaging can be processed at much smaller test volumes depending on current stock.

Q3: How does DongOu guarantee the durability of LCD panels in extreme climates?
