A KY-006 passive buzzer on a 3-pin breakout. Passive is the important word: unlike an active buzzer, which has its own oscillator and can only make one fixed beep, this one produces whatever frequency you feed it - so your code picks the pitch. It works well from about 1.5 to 2.5 kHz, driven straight off a microcontroller pin with tone() or a PWM output. Use it for melodies, multi-tone alarms, key clicks and audible feedback.
Key features
- Passive - you supply the tone, not the buzzer
- Useful range approx. 1.5-2.5 kHz
- Drives from tone() or a PWM pin
- 3-pin header: S, middle unused, -
- Works on 3.3V and 5V logic
- Board approx. 18.5 x 15 mm
