Description
The 0.28″ Dual LED Voltmeter Ammeter is a compact, reliable, and easy-to-use digital meter for monitoring both DC voltage (0–100V) and current (0–10A) simultaneously. Featuring a bright red LED for voltage and a blue LED for current, this dual-display module is ideal for power supply testing, battery monitoring, and DIY electronics.
With its small form factor and real-time dual measurement capabilities, it’s perfect for projects where both voltage and current need to be monitored at a glance.
