Audio Amplifier Modules

The MAX98357 I2S Digital Audio Amplifier Module is a compact Class-D audio solution that combines a digital-to-analog converter (DAC) and speaker amplifier in one board. It accepts digital audio through an I2S interface and delivers up to 3.2W output into a 4-ohm speaker at 5V. Designed for use with ESP32, Raspberry Pi, and other compatible microcontrollers, it is ideal for smart speakers, voice assistants, audio playback systems, and embedded electronics projects.
