High Quality Active / Passive Buzzer Module – 3.3 V ~ 5 V
Upgrade your Arduino projects, smart‑car kits, and DIY electronics with this versatile buzzer module. Designed for both active and passive operation, it delivers clear, crisp tones at a wide voltage range (3.3 V – 5 V), making it the perfect sound sensor and alert device for hobbyists and engineers alike.
Key Highlights
- Dual‑Mode Functionality: Works as an active buzzer (self‑oscillating) or a passive buzzer (requires external tone generation) for maximum flexibility.
- Wide Voltage Compatibility: Operates reliably from 3.3 V to 5 V, ideal for Arduino Uno, Nano, Mega, ESP32, Raspberry Pi Pico and other 5 V/3.3 V boards.
- Low‑Level Trigger Input: Simple HIGH/LOW control pins let you drive the buzzer directly from a digital output or a PWM pin.
- Compact, SMD‑Ready Design: Small footprint (15 mm × 12 mm) fits tight enclosures and breadboard prototypes.
- Durable Construction: High‑quality piezo element and robust PCB ensure long‑term reliability in demanding projects.
- Easy Integration: Pre‑soldered pins and clear labeling reduce wiring errors and speed up assembly.
