The Passive Buzzer Module 3.3V/5V is a compact sound-generating module designed for microcontroller and embedded system projects. Unlike active buzzers, this passive buzzer requires a PWM or frequency signal from the controller to generate tones, melodies, alarms, and sound effects. It is fully compatible with both 3.3V and 5V systems, making it suitable for use with Arduino, ESP32, Raspberry Pi, STM32, NodeMCU, and other development boards. This module is widely used in DIY electronics, robotics, automation systems, educational projects, IoT devices, security alarms, and notification systems. Its simple interface and compact design make it easy to integrate into breadboards and prototype circuits.
