Passive Buzzer Module (3.3V- 5V)

Description

The Passive Buzzer Module is an electronic sound module that generates tones when driven by a Pulse Width Modulation (PWM) or frequency signal from a microcontroller. Unlike an active buzzer, it does not contain a built-in oscillator, allowing you to produce different tones, melodies, and sound effects by varying the output frequency.

This module is perfect for Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and other development boards. It is widely used in robotics, IoT projects, musical applications, alarms, and educational electronics, making it an excellent choice for projects that require customizable audio output.

Its compact design and simple interface make it easy to integrate into breadboard prototypes and embedded systems.
