MAX98357 I2S 3W Class D Audio Decoder Module

High-Efficiency MAX 98357 I2S 3W Class D Audio Decoder Module for ESP32, Raspberry Pi & Arduino

Note: This modules comes with Soldered and Unsoldered version, we ship it randomly.

The MAX98357 I2S Class D Audio Decoder Module is a compact, high-performance amplifier that converts I2S digital audio input into powerful analog audio output. Designed for projects using ESP32, Raspberry Pi, Arduino, or other microcontrollers, it delivers crisp, clear sound output up to 3W while maintaining excellent power efficiency.

This module simplifies audio integration in digital systems by removing the need for a separate DAC (Digital-to-Analog Converter) and amplifier, making it ideal for IoT devices, smart speakers, and embedded audio applications.
