Description

PCB active buzzer module – 3.3V~5V

PCB active buzzer module with 3 leads: GND, I/O and VCC in the form of goldpin pins. Convenient way to install buzzer in your own projects. Triggered by a high state – supply voltage 3V – 5V.

Thanks to the control by the transistor, the microcontroller will not be loaded with current that could burn the digital channel. Loud and easy-to-use buzzer.
