Good value, clear instructions
Solid build quality for the price. The silkscreen labeling on the PCB makes wiring very easy. I deducted one star only because the included header pins were slightly bent, but they straightened out fine.

Works as described
No complaints here. It handles the 5V input well without overheating. The sound frequency is fixed since it's an active buzzer, which is exactly what I needed for a simple alert system.

Loud and reliable
I used this for a door alarm project. It triggers instantly and the tone is consistent. The active buzzer type means I don't need to generate a frequency in code, just a simple HIGH/LOW signal.

Compact and effective
Small footprint fits perfectly on my custom sensor board. The mounting holes align standardly. Delivery was fast and the packaging protected the components well.

Perfect for my Arduino robot car
This buzzer module worked flawlessly with my 5V Arduino setup. The ability to switch between high and low level trigger via the jumper cap is a huge plus. Sound is loud enough to be heard clearly even when the motors are running.

Essential component for beginners
Great for learning digital output control. The LED indicator helps visualize when the trigger is active, which is helpful for debugging circuits. Highly recommended for student projects.
Q: Is the volume adjustable on this module?
A: No, the volume is fixed by the internal design of the active buzzer component. If you need variable volume control, you would need to use a passive buzzer with PWM control or add an external amplifier circuit.
Q: How do I change the trigger mode from High to Low?
A: There is a small jumper cap on the board labeled 'H' and 'L'. Simply move the jumper cap to the 'L' position to set it to Low Level Trigger. Ensure the power is disconnected before adjusting the jumper.
Q: Can this module be used with a 3.3V microcontroller like the ESP32?
A: Yes, it can. While the module is rated for 5V, many users successfully drive the signal pin with 3.3V logic from an ESP32. However, for optimal volume and reliability, powering the VCC pin with 5V is recommended while keeping the signal logic compatible.
Q: What is the difference between this active buzzer and a passive one?
A: This is an active buzzer, meaning it has an internal oscillating source. You only need to supply power to make it sound. A passive buzzer requires an external square wave signal (PWM) to generate sound, allowing you to change the tone frequency.
Q: Does this come with male header pins soldered?
A: The module typically comes with the header pins included in the package but not pre-soldered, allowing you to choose the orientation or use female headers if preferred. Some batches may arrive pre-soldered depending on stock.
