This low-cost miniature piezo buzzer features a built-in drive circuit, allowing it to produce a clear, consistent tone from a simple DC supply. With flying leads for easy installation, it is ideal for alarms, indicators, and general-purpose audio signalling.
Unlike passive piezo elements, this version requires no external oscillator or PWM signal. Simply connect it to a suitable DC voltage and it will generate its rated tone automatically.
Supplied as a pack of 10, making it suitable for classroom use, prototyping, and production builds.
If your project requires a passive buzzer that you can drive with your own frequency source, you can find one here.
