Mini Dual LED Voltmeter Ammeter – DC 0-100V 10A Display
Mini Dual Display Digital Voltmeter & Ammeter – DC 0–100V / 10A
Monitor both voltage and current at a glance with this compact 4-digit, 5-wire mini digital voltmeter ammeter. Featuring a bright dual LED display, this all-in-one meter is ideal for electronics hobbyists, DIY builders, solar setups, battery monitoring, and workshop bench power supplies. Despite its tiny footprint (just 48×28 mm), the 0.28-inch LED digits are easy to read even in low-light environments.
Key Features
- Dual Measurement: Simultaneously displays DC voltage (0–100V) and current (0.000–9.999A) on a twin LED readout.
- 4-Digit Precision: High-resolution 4-digit display delivers clear, accurate readings for both voltage and amperage.
- Wide Voltage Range: Measures DC 0–100V; operates on a working supply of DC 4V–30V.

Frequently Asked Questions
Q: What is the maximum voltage this digital voltmeter ammeter can measure?
A: This mini digital voltmeter ammeter can measure DC voltages from 0 to 100V, making it suitable for a wide range of low-voltage DC applications including batteries, solar panels, and bench power supplies.
Q: Does this voltmeter ammeter need a separate power supply to operate?
A: Yes, the module requires a working supply voltage of DC 4V–30V to power its LED display. This is separate from the circuit being measured and is typically wired in via the dedicated power wires in the 5-wire harness.
Q: Can this dual LED meter be mounted inside a project enclosure or panel?
A: Absolutely. The compact 48×28 mm body is designed for panel mounting, making it easy to embed into custom enclosures, control boxes, or DIY power supply builds for a clean, professional look.
