Overview
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. 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.
