Mini Piezo Buzzers for Electronic Projects – 3V, 5V & 12V Models

Our Mini Piezo Buzzers are compact, reliable acoustic indicators suitable for a wide range of electronic projects, alarms, timers, and embedded systems. These buzzers produce a clear, sharp tone while drawing very little current, making them ideal for battery-powered or low‑power designs.

Available Voltage Models

We stock Mini Piezo Buzzers in three voltage options to suit your application:

• 3 V Piezo Buzzer – Ideal for microcontroller circuits, wearables, and low‑power devices.
• 5 V Piezo Buzzer – Suitable for Arduino projects, logic‑level circuits, and general electronics.
• 12 V Piezo Buzzer – Provides a loud output, perfect for alarms, automotive circuits, and higher‑voltage systems.
