KY-006 Passive Buzzer Module

The KY-006 Passive Buzzer High Level Module is a versatile, programmable sound output breakout board designed for Arduino, ESP32, ESP8266, Raspberry Pi, and other popular microcontroller platforms. Unlike active buzzers, the KY-006 features a passive buzzer element that requires an externally generated square wave signal to produce sound — giving you full control over tone, pitch, and melody through your code.

This flexibility makes the KY-006 ideal for a wide range of applications including alarm systems, notification tones, musical note generation, and interactive sound feedback in DIY electronics projects. Its high-level trigger design ensures straightforward interfacing with any digital output pin, and no additional components are required for operation.

With its compact 3-pin interface — signal, power, and ground — the module is fully breadboard-compatible and integrates seamlessly into both prototyping setups and finished enclosures. Whether you’re a student exploring microcontroller programming or a seasoned maker building a custom alert system, the KY-006 delivers reliable, flexible audio output in a clean plug-and-play format.
