This small active buzzer will give you a long and loud 2kHz beep when you apply a power of 5V. This buzzer does not require an external oscillator as there is a driver that makes it oscillate at 2kHz when powered. The buzzer is driven from a transistor so you can get the full power of the buzzer volume.
- Input Voltage: 5V
- Working Current: < 25mA
- 1x Active Buzzer Module
