Apply 3V to 5V to this buzzer module to produce a loud 2KHz sound. Unlike a plain piezo buzzer, it includes driver circuitry that makes it oscillate at 2KHz automatically, so no AC signal is needed. Note that the frequency cannot be changed.

• Dimensions (excluding pins): 12mm diameter, 9.7mm tall
• Pin length: 6mm, spaced 0.3″ apart

This breadboard-friendly buzzer is great for simple integration into electronic projects that require a loud and consistent tone.
