Connecting it up is easy – you only need ground, 3 to 5V power, and audio signal. The audio signal does not need to be AC coupled, we do that for you, and can range up to the power pin voltage (3 or 5V peak-to-peak).

The sound quality is good enough for music, tones, speech, whatever you like and volume can be adjusted with a small screwdriver.
