5V passive Buzzer

The 5V Passive Buzzer is an electronic audio signaling component that produces sound when driven by an external oscillating signal. Unlike active buzzers that contain a built-in oscillator, this passive buzzer requires a PWM or frequency signal from a microcontroller or external circuit to generate tones and melodies.

Operating at 5V DC, the buzzer is widely compatible with popular development platforms such as Arduino, ESP32, Raspberry Pi, STM32, and other embedded systems. Its ability to generate different frequencies makes it suitable for alarms, musical projects, notification systems, and educational electronics applications.

The buzzer features low power consumption, compact dimensions, and clearly marked polarity pins for easy and reliable installation. It is available in through-hole versions or mounted on breakout modules for convenient prototyping and PCB integration.
