Active buzzer with 3V rated voltage allows it to be directly driven by the GPIO ports of development boards such as Arduino and Raspberry Pi, eliminating the need for complex external circuitry. A stable 85dB sound pressure level provides clear and easily audible alerts in small devices without being overly harsh. With a diameter of only 12mm and a height of 9.5mm, it saves every millimeter of space for wearable devices, small robots, and compact PCB designs.
Feature
Direct Microcontroller Interface
With a rated voltage of 3VDC, this active buzzer can be directly driven by the 3.3V or 5V logic levels from an Arduino or Raspberry Pi GPIO pin. This eliminates the need for external transistors or drivers in most cases, speeding up your prototyping process.
Clear & Audible 85dB Tone
Provide effective user feedback without being overwhelming. The 85dB buzzer output is loud enough for personal devices and indoor environments, offering a clear and distinct alert tone for notifications, timers, or warnings.
Ultra-Miniature Footprint
12mm buzzer design with maximum flexibility. The tiny Φ12.0mm x 9.5mmH size allows you to embed it into the most space-constrained designs, from smart watches to compact sensor modules, without sacrificing functionality.
