Keyestudio RJ11 EASY-plug Active Buzzer Module for Arduino STEAM

The Keyestudio RJ11 EASY-plug Active Buzzer Module is a simple, digital sound-making component designed for rapid prototyping and STEAM education. Operating on a 3.3V to 5V range, it is perfect for students, hobbyists, and makers looking to add audio feedback to their Arduino projects without complex wiring.

Simple digital audio feedback

This active buzzer is the simplest sound-making module for your microcontroller projects. By applying a high or low level signal, you can easily drive the buzzer to create a loud beep.

Adjustable frequency and tones

By changing the frequency of the input signal, you can alter the pitch of the buzzer. This allows you to generate different electronic sounds and simple melodies for your interactive builds.

Wide operating voltage range

The module operates reliably on a working voltage of 3.3V to 5V. This makes it fully compatible with standard microcontrollers, including 3.3V and 5V development boards.

Easy RJ11 connection system

Featuring a high-quality RJ11 connector, this module integrates seamlessly into the EASY-plug ecosystem. This solderless design prevents wiring errors and speeds up classroom assembly.

Real-world appliance applications

Active buzzers are widely used in everyday household appliances like personal computers, refrigerators, and telephones. Integrating this module helps students understand how real-world electronic alerts are designed.
