0.36 Inch Mini Digital Voltmeter DC 2.7V-32V Green

The 0.36-inch Mini Digital Voltmeter is an ultra-compact, highly accurate 3-digit LED display module designed for real-time DC voltage monitoring from 2.7V to 32V. Featuring a simple two-wire configuration, this self-powered panel meter requires no external power supply, drawing its operating power directly from the voltage source it measures. With its bright green LED display and variable precision resolution, it provides clear and reliable readings even in low-light environments.

This miniature voltmeter is ideal for monitoring battery packs in DIY robotics, RC vehicles, solar power setups, and custom power supply units. It is fully compatible with lithium-ion batteries, lead-acid batteries, and various microcontroller projects (such as Arduino, ESP32, and Raspberry Pi systems) where precise voltage tracking is critical. Built-in reverse polarity protection ensures the module remains safe from damage during accidental wiring errors.

Features:

• Ultra-Compact Design: Features a tiny 0.36-inch 3-digit LED digital tube display, perfect for space-constrained panels.
• Wide Measurement Range: Accurately measures DC voltages from 2.7V to 32V.
• Two-Wire Connection: Simple red and black wire interface; self-powered by the target voltage source.
• Variable Precision: Automatically shifts decimal point position with 0.01V resolution below 10V and 0.1V resolution above 10V.
• Reverse Polarity Protection: Integrated safety circuitry prevents damage if the positive and negative leads are reversed.
• Bright Green Display: High-contrast green LED ensures excellent readability under various lighting conditions.
