3V Buzzer – 12mm PCB Mountable

This is a 3V Buzzer. It’s an Active Buzzer and is PCB mountable. Its small size makes it perfect for all types of DIY and breadboard projects as well as actual electronics production. This Buzzer module emit really loud sound when 3V is apply to it. Unlike a plain piezo, this buzzer does not need an AC signal. Inside is a piezo plus the driver circuitry that makes it oscillate at 2.4 KHz.
