The EasyBuzz Board is an accessory board featuring a piezo buzzer capable of emitting audio signals.
With such features, the Piezo Speaker add-on board is an ideal choice for adding an audio notification to any prototype device.
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 specified frequency. Piezo buzzer's resonant frequency is 3.8kHz (where you can expect it's best performance), but frequencies ranging between 2kHz and 4kHz can also be used. Buzzer driver can be provided with digital signal, or pulse-width modulated signal, where sound pitch is determined by the PWM frequency, and sound volume can be adjusted by changing PWM duty cycle.
The EasyBuzz Board supports both 3.3V and 5V systems.
