5V Active Buzzer Module

The Active Buzzer Module is a self-driven sound module that produces a continuous beep when power is applied. It has a built-in oscillation circuit, meaning it only requires a HIGH or LOW digital signal from a microcontroller to generate sound—no PWM or tone generation is needed.

This module is easy to interface with Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and other development boards. It can be used for notifications, warning systems, timers, interactive projects, and sound effects.

Its small size, low power consumption, and reliable performance make it an essential component for both beginners and experienced electronics enthusiasts.
