The YL-44 is a small buzzer module which operates around the audible 2 kHz frequency range. It is an active buzzer, which means that it produces sound by itself, without needing an external frequency generator. Taking the I/O pin LOW will turn the buzzer ON and taking this pin HIGH will turn the buzzer OFF (as will leaving this pin OPEN). This device could be controlled by PWM.


  • It and your Arduino/Chin Duino will be able to play melodies. This is a small buzzer for the Sensor Shield.
  • It creates different sounds based on the different frequencies of I/O toggling. 
  • All you need to do is to plug in the buzzer module to sensor shield and tell the function which pin you'd like to use the frequency you want to hear and the duration to play that frequency. 
  • Bring oscillation source 
  • Audion 9012 drive 
  • Work Voltage:3.3-5V 
  • Set bolt hole, easy to assemble 
  • PCB Dimension:3.3cm*1.3cm
