LED Voltage Meter (Green)

The LED Voltage Meter (Green) is a compact, standalone display module designed for real-time DC voltage monitoring. Measuring from 3.0V to 30V DC, it provides an easy power readout for makers, students, and hobbyists working on robotics, portable battery packs, and DIY electronics.

Wide DC voltage measurement range

This digital panel meter measures DC voltages from 3.0V up to 30V with approximately 1% accuracy. With a 2 Hz refresh rate, it delivers steady and reliable real-time readings for battery diagnostics and prototype monitoring.

Simple two-wire standalone connection

The module requires only a direct two-wire connection to the power source being measured. It operates without external control boards, signal conditioning, or extra circuitry, making it straightforward to wire into any project.

Clear green LED numeric readout

A bright green numeric LED display ensures quick visual monitoring of power levels, even within enclosures or equipment panels. Continuous voltage visibility helps track battery discharge curves and prevent unexpected power dropouts.

Embedded diagnostics and project integration

Its compact form factor fits easily into custom control panels, portable gear, and educational hardware setups. It serves as an effective diagnostic indicator for robotics power buses, mobile prototypes, and workbench power supplies.

Included in the box

The package includes one green LED voltage meter module ready for two-wire DC power monitoring.
