Description:
The main components of this module are an adjustable potentiometer, a speaker, and an audio amplifier chip; the main function is: it can amplify the output small audio signal, probably with a magnification of 8.5 times, and can pass through the built-in low-power speaker It can also be used to play music when it is played. As an external amplification device for some music playback devices, please pay attention to first turn the volume to the minimum when using it, and then increase it slowly to prevent burnout of the speaker.
When we connect the single-chip microcomputer for testing, we can input square waves of different frequencies and different durations at the signal end to edit the sound of the speaker.
At the same time, the module is compatible with various microcontroller control boards, such as ARDUIN0 series microcontrollers. When in use, we can stack a sensor expansion board on the microcontroller. The module is connected with its own wire, and then connected to the sensor expansion board, which is simple and convenient. At the same time, the module comes with a positioning hole with a diameter of 3mm, which is convenient for you to fix the module to other equipment.
