Product Overview

The Smart Speedometer for Motorcycle is an electronic instrument cluster that displays vehicle operating data and warning information. It is used in motorcycles, special-purpose vehicles, construction equipment, buses, and dashboard retrofit projects that require a centralized driver information display.

Core Advantages

1. 1000 cd/m2 Daylight-Readable Display

The 5-inch screen reaches 1000 cd/m2. In open cabs, exposed dashboards, and other positions where sunlight falls directly on the display, vehicle data and warning graphics remain readable without adding a deep sunshade.

2. -30°C to +85°C Temperature Performance

The speedometer powered on normally after 48 hours at -30°C and showed no functional issues after 72 hours at 85°C. This performance supports cold-weather starting, prolonged outdoor parking, and continuous operation on sun-exposed motorcycle dashboards.

3. CAN and GPIO Integration for Vehicle Data and Alarms

The CAN interface receives speed, coolant temperature, oil pressure, and other operating data from the vehicle controller. Multiple GPIO channels can connect warning lamps, sensors, and alarm outputs, allowing the display to present vehicle-specific data and fault alerts. Standby current below 2 mA limits battery consumption while the motorcycle is parked.

Customization Capabilities

Display Content and Warning Logic
Screen layouts can be developed for digital values, bar graphs, telltales, start-up pages, multilingual labels, unit systems, and color-coded alarms. Gauge ranges and warning thresholds can be matched to the vehicle data definition.
Communication and I/O Definition
CAN message mapping, data scaling, refresh logic, GPIO assignments, sensor inputs, and output behavior can be configured around the controller and wiring architecture used in the target vehicle.
Mechanical and Brand Integration
Bezel geometry, mounting points, rear housing, connector position, cable exit, logo placement, and surface finish can be matched to the dashboard opening and interior design.

Quality Control

Environmental Validation
Validation samples are held at -30°C for 48 hours and at 85°C for 72 hours. After each exposure, the unit is powered on and checked for screen startup, vehicle-data display, warning output, and visible deformation.
Software and Interface Approval
Firmware pages, warning logic, CAN data, and GPIO response are checked against the approved interface definitions. Applied input states must produce the programmed values and alarms before the software version is released.
Production Release Inspection
First-piece inspection confirms the approved display, housing, connector fit, and firmware version before production begins. Patrol checks and final power-on inspection are completed before packing.
