The M5Stack Audio Module is an audio-interaction expansion module for the M5Stack system, built on the ES8388 audio codec solution.
It offers dual 3.5mm jacks (one TRS jack for microphone input only, one TRRS jack for both microphone input and headphone output) to fulfil various recording and stereo playback needs.
An onboard STM32G030F6P6 microcontroller handles TRRS jack insertion detection and drives WS2812C RGB LEDs. Register configuration enables automatic switching between CTIA (American) and OMTP (International) wiring standards, ensuring compatibility with most headsets featuring integrated microphones
This module is ideal for smart voice, interactive art, educational entertainment, portable recording, and other audio applications.
