Adafruit STEMMA Speaker - Plug and Play Audio Amplifier
Description
This Adafruit STEMMA Speaker - Plug and Play Audio Amplifier got a class D audio amplifier on board.
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). You can use either the 3-pin JST socket or the alligator/sew-pads for this slim and portable package. The sound quality is good enough for music, tones, speech, volume can be adjusted with a small screwdriver.
