5V Mini Buzzer Active Piezo 12mm | 2 Pin Electronic Buzzer for Arduino

The 5V Mini Active Piezo Buzzer (12mm, 2 Pin) is a compact and easy-to-use sound indicator designed for Arduino, microcontroller, and electronics projects. As an active buzzer, it produces sound immediately when 5V DC is applied—no external signal or frequency generation required.

With its small 12mm diameter and low power consumption, this buzzer is ideal for alarm systems, notification alerts, timers, security projects, and DIY electronics. The 2-pin PCB-mount design makes it simple to integrate into breadboards and circuit boards.
