M5Stack Audio Module STM32G030 + ES8388

The M5Stack Audio Module enhances your projects with high-quality audio features in a compact, stackable format. It combines the powerful ES8388 audio codec with an STM32G030F6P6 microcontroller for controlling audio routing, LED display, and automatic detection of headset types. With dual microphone input, stereo headphone output (TRS and TRRS), and built-in RGB status LEDs, the module is ideal for voice control, audio recording, and interactive applications. The integrated microcontroller handles cable management and allows seamless switching between CTIA and OMTP standards. It supports numerous platforms such as Arduino, UiFlow1, and UiFlow2, allowing for quick and flexible integration. The RGB LEDs provide visual feedback, making the module interesting for gesture-controlled applications. Its low power consumption makes it suitable for mobile or energy-optimized scenarios. With a standardized M5Stack form factor, the module can be easily integrated into existing setups.
