Description
Module Audio is an audio-interaction expansion module for M5Stack, built on the ES8388 audio codec solution. It offers dual 3.5 mm jacks (TRS audio jack supports only input, while TRRS combo jack supports both microphone input and headphone playback.) to fulfill 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.
