decoding chip N9301 and a microSD card slot. Users can control the playback of MP3 files on the microSD card through Grove's UART interface. The audio signal is output through a 3.5mm jack, providing clear audio output. This product is suitable for smart voice interaction devices (such as smart home controllers, voice tour guides), industrial automation alarm systems, medical equipment voice prompt terminals, STEAM education, and other scenarios. It can meet the demands of multiple industries for high-quality audio playback and flexible control, especially for embedded projects that require audio triggering through serial port instructions and integrated miniaturized audio solutions.\u003c\/p\u003e\n\u003ch2 id=\"features\" data-id=\"Features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eN9301 audio decoding chip\u003c\/li\u003e\n\u003cli\u003eUART communication interface\u003c\/li\u003e\n\u003cli\u003e3.5mm stereo jack\u003c\/li\u003e\n\u003cli\u003eSupports MP3 and WAV audio formats\u003c\/li\u003e\n\u003cli\u003eSupports FAT16\/FAT32 file systems\u003c\/li\u003e\n\u003cli\u003eMaximum support for 32GB microSD card\u003c\/li\u003e\n\u003cli\u003eDevelopment platforms\n\u003cul\u003e\n\u003cli\u003eUiFlow1\u003c\/li\u003e\n\u003cli\u003eUiFlow2\u003c\/li\u003e\n\u003cli\u003eArduino IDE\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"includes\" data-id=\"Includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Unit AudioPlayer\u003c\/li\u003e\n\u003cli\u003e1 x HY2.0-4P Grove connection cable (20cm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"application\" data-id=\"Application\"\u003eApplication\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIntelligent voice interaction devices (such as smart home control centers, voice guides)\u003c\/li\u003e\n\u003cli\u003eIndustrial automation alarm systems\u003c\/li\u003e\n\u003cli\u003eMedical device voice prompt terminals\u003c\/li\u003e\n\u003cli\u003eSTEAM education\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"specifications\" data-id=\"Specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"table-container\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio decoding chip\u003c\/td\u003e\n\u003ctd\u003eN9301\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage interface\u003c\/td\u003e\n\u003ctd\u003emicroSD card slot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication method\u003c\/td\u003e\n\u003ctd\u003eUART serial communication.
