6.8 inch Display SCJ6877-E

6.8 inch display SCJ6877-E, new product from SIAECOSYS, which redefines in-vehicle data visualization and user interaction, tailored to meet the diverse needs of modern electric and hybrid vehicles.
With its wide compatibility, intuitive design, and robust performance, the SCJ6877-E is a good choice.

Unmatched Versatility: Designed for All Vehicle Types & Battery Systems
This 6.8 inch display stands out with its exceptional adaptability, starting with a wide operating voltage range of DC12-150V—making it suitable for a broad spectrum of vehicles, from small electric scooters to medium-duty electric trucks. 

A key highlight is its universal battery power display, which seamlessly supports both lithium-ion and lead-acid batteries. This eliminates the need for separate speedometers for different battery types, simplifying installation and reducing costs for vehicle manufacturers and modifiers.

To cater to global markets, this speedometer offers flexible unit switching between metric (km/h, km) and imperial (mph, miles) systems, alongside multi-language support (Chinese/English). This ensures a localized user experience, whether the vehicle is deployed in Asia, Europe, or North America.

Intuitive Interaction & Rich Functionality: Beyond Basic Speed Tracking
4 Switchable Main Interfaces (UI1-UI4): Users can customize their view to prioritize critical data—from speed and RPM to battery level and trip mileage—via key + TP full-touch control. A one-key screen lock function prevents accidental operation during driving, enhancing safety.

Seamless Bluetooth Projection: No app installation is required for iOS or Android devices. Simply connect to the Bluetooth name “METER - CJ****” (last 4 digits random) to mirror phone screens, enabling navigation, calls, and music playback directly on the 6.8 inch display.
For iOS, it supports CarPlay; for Android, it works with Android Auto, ensuring hassle-free connectivity.

Multimedia & Utility Tools: The built-in FM radio provides on-the-go entertainment, while an 8W/4Ω * 2-channel power amplifier delivers clear audio. A USB port enables easy software upgrades, ensuring the speedometer stays up-to-date with the latest features.

Robust Performance & Reliable Data Monitoring
Engineered for durability, the SCJ6877-E boasts an IP65 protection rating, making it resistant to dust and water splashes—ideal for both indoor and outdoor vehicle use. It operates flawlessly in a temperature range of -20°C to +70°C, adapting to harsh weather conditions from cold winters to hot summers.

The speedometer’s high-resolution 480*1280 pixel display ensures sharp, easy-to-read data even in direct sunlight. Beyond speed and mileage (ODO/TRIP), it monitors critical vehicle metrics in real time, including:
· Battery level (10-grid display for precision) and undervoltage alerts
· Motor RPM, throttle status, and ECU fault codes
· Tire pressure (compatible with 4 tire pressure sensors, with abnormal alerts)
· Turn signals, high beams, and parking status

For backend customization, users can access a settings interface within 20 seconds of startup (via long-pressing the screen’s upper right corner). Here, parameters like voltage calibration, speed limits (1st/2nd/3rd gear), and remaining range display (requires BMS data) can be adjusted to match specific vehicle configurations.

Easy Installation & Controller Compatibility
The SCJ6877-E simplifies installation with clear outlet port definitions, supporting both One-Line Communication and CAN Communication controllers. Default parameters are provided for 12-inch wheels (e.g., One-Line: Speed Pulse = 13, Pulse Base = 40000; CAN: CAN18, Speed Coefficient = 2000), and speed deviations can be fine-tuned using the built-in adjustment coefficient tool.

A detailed wiring guide is included, with color-coded wires for turn signals, speakers, and battery connections—ensuring installers can set up the speedometer quickly and accurately.
