Feature

●【Customizable Sound】The passive buzzer alarm module allows you to control the sound frequency, creating melodies like Do, Re, Mi, Fa, Sol, La, Si.
●【Durable Build】Crafted with high-quality PCB material, the compact passive buzzer module is lightweight, wear-resistant, and built to last.
●【Easy Installation】Designed with installation holes (bolts not included), the passive buzzer module can be easily fixed in place. It can also share a control port with an LED.
●【Wide Voltage Compatibility】Connect the buzzer module externally to a 3.3V-5V power source, making it compatible with both 5V and 3.3V microcontrollers.
●【No Internal Oscillation Source】This passive buzzer module lacks an internal oscillation source, making it unsuitable for producing sound with a DC signal.


Description

Feature:
1. Controllable Frequency: The passive buzzer alarm module sound frequency is controllable, and the effects of Do, Re, Mi, Fa, Sol, La, Si can be made.
2. Without Oscillating Source: The passive buzzer module does not have an internal oscillation source, so if a DC signal is used, it cannot be made to whistle.
3. Easy to Install: The passive buzzer module is specially designed with holes for fixing with bolt (not included), convenient to install. Can share a control port with LED.
4. Working Voltage: External connection of 3.3V?5V voltage, the buzzer module can be directly connected with 5V micro controller and 3.3V micro controller.
5. High Quality Material: The compact passive buzzer module is carefully manufacture by high quality PCB material, wear resistant, lightweight and durable.
