Introduction
The keyestudio power amplifier module integrates an adjustable potentiometer, a speaker, an audio amplifier 8002B chip and a 3pin header interface.
It can amplify the small audio signal output, about 8.5 times magnification, and can play it out via a small power speaker.
It can also be used to play music, or used as an external sound amplification device for some music playback devices.
Pay close attention that should adjust the sound volume to a minimum before use, then slowly increase the speaker volume, preventing from burning the speaker.
When testing, after connected to microcontroller, input square waves of different frequency and different duration at the signal end, so that can edit the sound produced from the speaker.
