Description
Product Overview
The DIYables Passive Piezo Buzzer Module is a lightweight, compact transducer designed for hobbyists and educators who need reliable sound output in their projects. Each module weighs only 0.317 ounces and measures 3.94 x 2.8 x 0.67 inches, making it easy to fit into tight enclosures. Operating on a broad voltage range of 3.3V to 5V, the buzzer produces sound based on the frequency of the input signal, allowing you to craft anything from simple beeps to complex melodies using PWM control. The package includes two identical modules, giving you flexibility for stereo effects or backup units.
Usage
These buzzers are perfect for a variety of applications, including Arduino‑based alarms, ESP32 notification systems, Raspberry Pi sound effects, and classroom electronics kits. Their low power consumption ensures they can run for extended periods on battery‑powered projects, while the straightforward two‑wire connection (signal and ground) simplifies integration into any prototype. Whether you are building a smart home device, a robotic toy, or an interactive art installation, the passive piezo buzzer delivers clear, adjustable tones with minimal circuitry.

FAQ
Can I use this buzzer with a 5V Arduino?
Yes, the buzzer operates safely within a 3.3V to 5V range, making it fully compatible with standard Arduino boards.
Do I need an external driver circuit?
No external driver is required; the buzzer is passive and driven directly by PWM signals from your microcontroller.
What is the difference between active and passive buzzers?
Active buzzers contain an internal oscillator and emit a fixed tone when powered, while passive buzzers require an external signal to produce sound, giving you control over pitch and melody.
Is the buzzer suitable for continuous operation?
Yes, its low current draw allows for continuous use without overheating, provided the supply voltage stays within the specified range.
Are there example code libraries available?
DIYables provides example sketches for Arduino, ESP32, ESP8266, and Raspberry Pi on their website, making integration straightforward.
