Add some audible feedback to your project with this tiny active buzzer module. The module is very simple to operate. Just connect it to your microcontroller and send a square wave of 2K ~ 5K frequency to the middle pin and the buzzer will sound or in other words HIGH signal means buzzer is on and LOW means it’s off. Depending on frequency of the HIGH signal sent the buzzer sound will be higher or lower pitched. 3.3V – 5V drive voltage means that the buzzer can be connected to a wide range of micro controllers such as Arduino, Raspberry Pi, BeagleBone, AVR and many more. Features a mounting hole for easy installation.
