Product Description
Passive Buzzer Module is an audio signaling device that requires an external PWM or square wave signal to produce sound. Unlike active buzzers, it does not have an internal oscillator, allowing you to vary the frequency to create different musical tones, melodies, or complex alerts. It is commonly used for user interface feedback, musical robotics, and custom alarm systems. Compact and efficient, it easily interfaces with Arduino, ESP32, or Raspberry Pi using a single digital I/O pin.
