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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e- M5Stack Chain series\u003cbr\u003e- GMI4015P-2C microphone sound acquisition\u003cbr\u003e- Supports 12-bit ADC sampling of sound signals and threshold triggering\u003cbr\u003e- STM32G031G8U6 main controller\u003cbr\u003e- 1 x RGB LED\u003cbr\u003e- UART serial daisy-chain communication protocol\u003cbr\u003e- 2 x HY2.0-4P expansion interfaces for connecting Chain series devices\u003cbr\u003e\u003cbr\u003e\u003cb\u003eApplications:\u003c\/b\u003e\u003cbr\u003e- Environmental sound detection\u003cbr\u003e- Sound threshold triggering\u003cbr\u003e- Voice-controlled interactive devices\u003cbr\u003e- Smart home sound sensing\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003cbr\u003e- MCU: STM32G031G8U6\u003cbr\u003e- Power input: DC 5V\u003cbr\u003e- Communication: UART 115200bps at 8N1\u003cbr\u003e- Interface: 2 x HY2.0-4P\u003cbr\u003e- Microphone: GMI4015P-2C\u003cbr\u003e- Operational amplifier: SGM321YC5\/TR\u003cbr\u003e- RGB LED: 1 x WS2812C-2020\u003cbr\u003e- Sound Signal: 12-bit ADC sampled value, threshold trigger status\u003cbr\u003e- Operating power consumption: 5V at 35.54mA (MIC active, white LED always on)\u003cbr\u003e- Product size: 24.0 x 24.0 x 16.0mm\u003cbr\u003e- Product weight: 5.7g\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Chain Mic\u003cbr\u003e- 1 x Chain Bridge\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 790px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/106009\/106009-01.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Thanksbuyer","offers":[{"title":"Default Title","offer_id":41307762163761,"sku":"106009","price":19.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/20261028092033_dd3d2065.jpg?v=1793180097"}],"url":"https:\/\/www.thanksbuyer.com\/ru\/collections\/m5stack-chain-mic.oembed","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
