Digital Instrument Cluster for Electric Two- & Three-Wheelers
engineered end-to-end.
A compact digital speedometer and odometer for electric scooters, motorcycles and e-rickshaws. A custom high-contrast segment LCD shows road speed in large digits, total distance, two trip meters, battery state of charge as a bar graph and percentage, and turn-indicator arrows. The board reads wheel speed from a hall-effect or reed sensor (or speed pulses from the motor controller), measures the traction battery directly, and stores the odometer reading in non-volatile memory so it survives battery removal. Wide-range input, reverse-polarity and load-dump protection let it run straight from the vehicle supply, and the same design is adapted to different dashboards, battery voltages and wheel sizes.
Round digital odometer display.
A compact round instrument for vehicles with a circular dashboard opening: speed in large digits, odometer and trip, a segmented battery gauge, turn indicators and headlamp status on a high-contrast LCD.
- Large 3-digit speed read-out
- ODO and TRIP distance
- Segmented battery level bar
- Turn-indicator and headlamp icons
- Fits round dashboard openings
What it does.
- Large-digit road speed in km/h, with configurable wheel size and pulses per revolution
- Total odometer plus Trip A / Trip B, resettable from the dashboard
- Battery state of charge as a 10-segment bar graph and percentage, calibrated for lead-acid or lithium packs
- Direct battery voltage measurement for 48 V, 60 V and 72 V systems
- Speed input from a hall-effect / reed wheel sensor or from the motor controller speed signal
- Left / right turn indicators, plus warning icons as required by the vehicle
- Odometer stored in non-volatile memory with wear-levelling and power-fail save — no reading lost on battery removal
- High-contrast segment LCD with white LED backlight, readable in direct sunlight and at night
- Wide-range input with reverse-polarity, over-voltage and load-dump protection for the vehicle electrical system
- Low quiescent current with the key off, so the cluster never drains the traction battery
- Compact single-board design with board-edge mounting for different dashboard housings
- One platform covering two-wheelers and three-wheelers (e-rickshaws and loaders)
Electronics first.
System thinking throughout.
