The Buzz 2 Click Board™ carries the CMT-8540S-SMT magnetic buzzer transducer. The buzzer's resonant frequency is 4kHz. The click is designed to run on either 3.3V or 5V power supply.
How Does The Buzz 2 Click Board™ Work?
The CMT-8540S-SMT magnetic buzzer is controlled by the PWM pin on the mikroBUS™ line.
You can create different sound patterns using the Sound library supported in our compilers, or utilize the microcontroller internal PWM module to create the signal for the buzzer. Signal frequency determines the sound pitch, and the duty cycle determines the amplitude (sound volume).
POWER SUPPLY SELECTION
Onboard VCCIO SEL zero-ohm resistor (SMD jumper) is used to determine whether 5V or 3.3V power supply is used. This resistor is placed in 5V position by default.
