## Description

A compact 3-wire voltage meter with a vivid green 3-digit 7-segment display. Reads 0–99.9VDC with 0.1V precision, making it perfect for monitoring battery levels, power supplies, and electronic projects. Mounting tabs allow easy attachment to enclosures or panels. The 3-wire design separates power from measurement — two wires power the display (4.5–28VDC) while the third wire connects to the voltage you want to measure. The built-in microcontroller reads the voltage against a stable reference and draws only 3–4mA. Key Features Wide Measurement Range – 0V to 99.9VDC 0.1V Precision – 3-digit 7-segment green LED display 3-Wire Design – Separate power and measurement connections Low Power Draw – Only 3–4mA Mounting Tabs – Easy panel or enclosure mounting Specifications Measurement Range: 0–99.9VDC Resolution: 0.1V Supply Voltage: 4.5–28VDC Current Draw: 3–4mA Display: 3-digit 7-segment (green LED) Wiring Red wire: Positive power supply (4.5–28VDC) Brown/Black wire: Common ground Orange/White wire: Voltage measurement input Ideal For Battery voltage monitoring Power supply readouts Breadboard and enclosure projects RC hobby battery tracking Package Contents 1× Mini 3-Wire Volt Meter (0–99.9VDC, green display)
