Description Chain MIC is a sound acquisition node in the M5Stack Chain series. It features a built-in GMI4015P-2C microphone, an SGM321YC5/TR operational amplifier, and a programmable RGB LED. It supports 12-bit ADC sampling of sound signals and threshold triggering, making it suitable for applications such as environmental sound detection, voice-controlled interaction, and device status indication. It integrates an STM32G031G8U6 main controller and uses a UART serial daisy-chain communication protocol. Its two HY2.0-4P expansion interfaces allow more Chain series devices to be connected, enabling richer sound sensing and interactive applications.
