ky-006 Passive Speaker Buzzer Module

The KY-006 Passive Speaker Buzzer Module is a compact and versatile module designed for audio signaling and sound generation in electronics projects. Unlike active buzzers, this module is passive, which means it requires an external square wave signal (PWM) to produce sound, giving users full control over frequency and tone for customized audio alerts.

It is ideal for alarms, notifications, electronic learning projects, and DIY embedded systems. Its small footprint and simple interface make it easy to integrate with Arduino, ESP32, Raspberry Pi, or other microcontroller-based projects.
