It is designed to act as a standalone smart hub, capable of interfacing with online large language models (like DeepSeek) for advanced AI speech interaction. With 8MB of onboard PSRAM and 16MB of external Flash, it easily handles complex graphics on the 3.49-inch IPS display while managing background IoT tasks.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 id=\"advanced-audio-and-motion-sensing\" class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eAdvanced Audio and Motion Sensing\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eThe board integrates a complete audio and motion sensing suite directly into its compact footprint. It features an ES7210 ADC with a dual-microphone array for echo cancellation and noise reduction, alongside an ES8311 DAC for clear audio playback. Additionally, the onboard QMI8658 6-axis IMU allows for precise gesture recognition and motion tracking, making it ideal for interactive handheld devices or wearable prototypes.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 id=\"technician-tip\" class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eTechnician Tip\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eWhen setting up this board for the first time, ensure your TF (MicroSD) card is formatted to FAT32, as other formats will not be recognized for data expansion or media playback. Our Sun Cheong Computer Co. Ltd. technical team recommends utilizing the built-in Type-C port not just for programming (via Arduino IDE or ESP-IDF), but also for safely charging the included 18650 lithium battery. Always double-check the battery polarity before inserting it into the internal holder to prevent damaging the power management circuit.\u003c\/span\u003e\u003c\/p\u003e","brand":"Waveshare","offers":[{"title":"Default Title","offer_id":68285802283159,"sku":"21CU000189","price":320.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/esp32-s3-touch-lcd-side-profile-buttons.jpg?v=1794129192","url":"https:\/\/scccltd.com\/products\/waveshare-esp32-s3-3-49-inch-touch-lcd-case","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
