DC 0–100V 10A Digital Voltmeter Ammeter | Dual LED Voltage & Current Meter Panel for Arduino, Solar & Battery Monitoring Systems

The DC 0–100V 10A Dual Digital Voltmeter Ammeter is a compact, high-precision two-in-one voltage and current measurement module designed for monitoring DC power systems. It features dual LED displays — red for voltage and blue for current — allowing real-time monitoring of both parameters simultaneously.

This panel meter is ideal for power supplies, battery monitoring, solar systems, DC motor drivers, and DIY electronics projects. It can measure voltages up to 100V DC and currents up to 10A DC, making it perfect for medium-range DC applications.

The module includes pre-wired connections for quick setup and features a 0.28″ bright LED display for easy readability even in low-light conditions.
