Active Buzzer Module 3.3~5V Low Level Trigger Buzzer 3 Pin Control Board,Driven by S8550 Transistor

  • Internal Source: The active buzzer has an internal source of oscillation, so it will be called as soon as it is energized.
  • 3 Pin Control: The module is driven by S8550 transistor.Adopts 3 pin control.
  • Convenient to Use: Program control is convenient. A high-low level of the MCU can make it sound,which the passive buzzer can’t.
  • Instructions for Use: When the I/O port is input low, the buzzer sounds.
  • Easy to Install: Fixed bolt holes for easy installation.
