This Breakout Board features a piezo speaker capable of emitting audio signals. Buzzer’s resonant frequency is 3.8kHz (where you can expect it’s best performance). On-board buzzer driver is connected to both digital (CS) and to PWM line. You can use either of those two to provide the signal from the microcontroller to the buzzer driver. Board is set to use 5V power supply by default.
Tenet’s Buzzer breakout is an electrical device that makes a buzzing noise and is used for signaling. It’s a two terminal device, positive terminal is usually GPIO pin of a microcontroller and negative terminal is tied to GND.
