Voltage Indicator Module - What it does Displays a voltage level for battery monitoring or for use with signals to implement a VU meter for audio level or similar applications. - Key features Adjustable voltage range with an LED display for easy reading. Wide operating supply from 3.5 V to 10 V. Note: a limit of 12 V is hazardous and not recommended. Compatible with both AC and DC voltages. - Use scenarios Monitor the state of charge in portable devices or battery-powered projects. Interface with audio gear to create a VU meter that visualizes loudness or signal strength. Use in microcontroller projects or lab setups to monitor and display power rails or other voltages. - Why this helps Provides a clear, at-a-glance voltage readout with flexible power input. Enables easy integration into a variety of systems that require voltage monitoring or visual indication. Keeps operation within a safe voltage range while supporting both AC and DC sources.
