Active Buzzer Module 3-5v

The Active Buzzer Module is an easy-to-use electronic sounder designed to provide audible indications in microcontroller and DIY electronics projects. When supplied with the appropriate voltage, the active buzzer generates a continuous sound without requiring a separate tone-generation circuit.

The module operates from 3.3V to 5V DC, making it suitable for many Arduino and microcontroller-based systems. An integrated 8550 transistor drive circuit provides a convenient way to control the buzzer.

Its compact PCB measures approximately 34.28 × 13.29 × 11.5 mm and includes a 2.6mm fixed bolt hole for mounting in project enclosures or electronic assemblies.

How It Works

The Active Buzzer Module contains an internally driven buzzer that generates an audible tone when power is applied. The integrated 8550 transistor drive allows the buzzer to be controlled conveniently within an electronic circuit.

When connected to a suitable power supply or controlled through a compatible microcontroller circuit, the buzzer produces a continuous audible signal. This makes it useful for indicating events such as completed timers, detected conditions, button presses, or alarm states.

Important Notes

• Use a supply voltage within the specified 3.3V–5V DC range.
• The active buzzer produces a continuous sound when properly powered.
• Check the module's polarity and connections before applying power.
• The sound output and performance may vary depending on the supplied voltage and individual module.
• Product appearance and component arrangement may vary slightly between production batches.
• Please allow 5% measuring deviation due to manual measurement.
• Product Images are shown for illustrative purposes only and may differ from the actual product.
