NOTE: The compatible piezo sounder comes in the same package as this Click board™.
HOW DOES IT WORK?
Piezo Driver Click is based on the PAM8906, a piezo sounder driver with self-excitation mode from Diodes Incorporated. It features automatic shutdown and wake-up control, low operating current, very short turn ON/OFF, over-voltage protection, over-current protection, and more. This driver operates with an external PWM input. It can drive a two-terminal or three-terminal piezo sounder, and selection can be made over the TERMINAL SEL jumper. The piezo sounder can be connected over the 3-pin screw terminal, labeled differently for both available options. In addition, you can use VOUT to power up the piezo sounder.
Piezo Driver Click uses a PWM input pin to communicate with the host MCU. If used as an external PWM control, the PWM input will be amplified and driven to the output terminal. It can also be used for automatic wake-up and shutdown control.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
