MAX98357 I2S 3W Class D Amplifier Audio Decoder Module

MAX98357 I2S 3W CLASS D Audio Amplifier Module accepts digital audio through the I2S interface and converts it to an analog output signal and amplifies it to allow direct speaker connection. It combines an I2S D/A converter with an audio amplifier on one board.
MAX98357 I2S 3W CLASS D Audio Amplifier Module is suitable for Raspberry Pi. By default, the stereo signals (L + R) are mixed to form an output signal. The behavior can be changed using a resistor so that only L or R is output.
