description 1 3 Pinout 2 4 Code example Arduino 2 5 Code example Raspberry Pi 2 Pictures Technical data / Short description This Buzzer creates a sound with a frequency of 2,5k Hz. 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.
