3.3-5V Active Buzzer Module

Features

Operating Voltage: 3.3V to 5V – Module works easily with both 3.3V and 5V microcontrollers like Arduino, ESP32, etc.

Built-in Oscillator – There are no need to send tone signals from the microcontroller; it generates sound by itself.

Easy to Use – Just give power and it starts buzzing; no complex code needed.

Compact Size – Small module that fits easily in your DIY or embedded projects.

Onboard Indicator Light (Optional) – Some versions have an LED that lights up when the buzzer is on.

Digital Signal Control – It can be turned ON/OFF using just one digital pin from a microcontroller.
