Active Buzzer Module 3.3V-5V

An Active Buzzer Alarm Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. Just like what you are viewing now, it is a 3.3V-5V DC Electronic Part Active Buzzer Module. Using top-quality material, it is durable in use. 

 

An 5V active buzzer rings out as long as it is electrified. Compared with a passive buzzer, it is a bit expensive but easier to control. Typical uses of buzzers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.

 

Module Interface Specification (3-wire)
+ External 3.3V-5V voltage (can be directly connected with the 5v and 3.3v MCU MCU)
– External GND out external microcontroller IO port.
