Passive Buzzer Module

The Passive Buzzer Module is a reliable digital transducer ideal for adding sound alerts to your electronics projects. Commonly used in computers, printers, copiers, alarms, digital toys, automotive electronics, and more, this module is a versatile component that can generate a range of tones depending on the input frequency.

Designed for easy integration, this PCB-mounted module is compatible with a 2.54mm pin pitch and works seamlessly with microcontrollers like Arduino. By switching the buzzer on and off at different frequencies—using delays or PWM—it can produce tones between 1.5 to 2.5 kHz. This allows you to create custom alert sounds that respond to programmatic changes in your project.

To operate, the Passive Buzzer Module requires a square wave input signal from the I/O pin of your microcontroller, making it a flexible and programmable sound solution for a variety of applications.
