Piezo Speaker Add-on Board, Configurable IDC10, 3.3/5 (EasyBuzz) US$3.00

Piezo Speaker Add-on Board, Configurable IDC10, 3.3/5 (EasyBuzz)

  • Piezo buzzer with 3.8 kHz resonant frequency
  • Piezo buzzer driver on board
  • Configurable IDC10 interface
  • Can be used on both 3.3V and 5V systems
  • The EasyBuzz Board features a Piezo Speaker capable of emitting audio signals. For the piezo buzzer to operate normally, it is necessary to generate a voltage signal of the specified frequency. The piezo buzzer's resonant frequency is 3.8 kHz, so the best sound quality is achieved using frequencies between 2 kHz and 4 kHz. The total usable range is 20 Hz to 20 kHz.

    The buzzer driver can be provided with a digital signal or a pulse-width modulated signal, where sound pitch is determined by the PWM frequency, and where sound volume can be adjusted by changing the PWM duty cycle.

    The board has a female IDC10 connector. DIP switches on the board allow you to configure which pin(s) will be used for the signal from your host system.

    Use in your own design

    While this board was created originally for mikroElektronika's development systems, it's certainly possible to use in your own project. To do so, you may want to pick up IDC10 box headers that you can solder onto your PCB, or an EasyTEST board to wire it up easily.
