KY-012 Active Piezo-Buzzer module

.............. 1 3 Pinout ............. 2 4 Code example Arduino ...........

Features

2,5kHz. The active Buzzer-module doesn't need a square wave, unlike the passiv module (KY-006), to create a sound. If it gets a minimum Voltage of 3.3V at its signal pin, the buzzer will create the square wave by itself.
