0.56inch 0-30V Three Wire DC Voltmeter Blue
This mini DC voltmeter, equipped with a clear LED display, is capable of measuring voltages up to 30V. Its compact design makes it easy to incorporate into a variety of projects. The voltmeter features three wires, predominantly red, simplifying the wiring process. For voltage measurements between 3.5V and 30V, you can merge the red and yellow wires for an easy connection, where the measured voltage also powers the voltmeter. Factory-calibrated for accuracy, the device includes a potentiometer on the back for fine-tuning, allowing you to adjust the displayed voltage by rotating it clockwise to reduce the value if needed.

0.56inch 0-30V Three Wire DC Voltmeter Blue Overview
The 0.56″ 0-30V Three Wire DC Voltmeter Blue is a compact panel-mounted LED meter designed to accurately measure DC voltages up to 30V. Its clear blue display and simple three-wire hookup make it ideal for electronics projects, power supplies, battery monitoring and DIY instrumentation.
Key Features of 0.56inch 0-30V Three Wire DC Voltmeter Blue
- High-contrast 0.56″ blue LED display for easy reading
- Wide DC voltage range from 0 to 30V
- Three-wire connection (red for Vcc, black for GND, yellow for sense)
- Self-powered operation when red and yellow wires are tied (3.5–30V)
- Factory-calibrated accuracy with rear potentiometer for fine adjustment
- Fast shipping across India from Zbotic
Applications and Use Cases
- Battery voltage monitoring in robotics and drones
- Solar panel output display in renewable energy setups
- Voltage indicator on bench power supplies
- Custom automotive or EV battery pack monitoring
- Integration with Arduino, Raspberry Pi or other microcontroller projects
How to Use 0.56inch 0-30V Three Wire DC Voltmeter Blue
Mount the voltmeter into a 0.56″ panel cutout and connect the black wire to ground. For self-powered operation on voltages between 3.5V and 30V, tie red and yellow wires together; the meter will use the measured voltage as its supply. To measure below 3.5V, provide an external 5–30V supply to red, connect black to ground, and feed the lower voltage signal to yellow. Use a small screwdriver on the rear potentiometer to fine-tune the displayed reading.

Frequently Asked Questions
What voltage range can this meter measure?
It accurately measures DC voltages from 0V up to 30V.
How do I calibrate the displayed voltage?
Use the potentiometer on the back of the meter. Gently turn it with a screwdriver to adjust the reading until it matches a known voltage reference.
Which wires are for power and sensing?
The red wire is the positive supply input (Vcc), black is ground, and yellow is the voltage sense line. Tie red and yellow together for self-powered measurement between 3.5V and 30V, or use an external supply on red for lower voltages.
