{"product_id":"espressif-esp-vocat","title":"Espressif ESP-VoCat","description":"\u003cp\u003eESP-VoCat is an intelligent AI development kit. It is suitable for voice interaction products that require large model capabilities, such as toys, smart speakers, and smart central control systems. The device is equipped with an ESP32-S3-WROOM-1 module, a 1.85-inch QSPI circular touch screen, dual microphone array, and supports offline voice wake-up and sound source localization algorithms. Combined with the large model capabilities provided by Amazon Nova, OpenAI, Xiaozhi AI, Gemini, etc. ESP-VoCat can achieve full-duplex voice interaction, multimodal recognition, and intelligent agent control, providing a solid foundation for developers to create complete edge-side AI application experiences.\u003c\/p\u003e\n\u003cp\u003eESP-VoCat’s main controller uses the Espressif ESP32-S3-WROOM-1-N16R16VA module, supporting 2.4 GHz Wi-Fi and Bluetooth 5 (LE) wireless connectivity. For storage, the entire device has 16MB PSRAM and 16MB Flash storage space, and is also equipped with a microSD card slot that can support up to 32GB, meeting the needs of voice interaction and multimedia processing. It features a 1.85-inch circular touch screen (360 × 360 resolution) with ESP32-S3 native touch sensors, providing an intuitive and rich interactive experience.\u003c\/p\u003e\n\u003cp\u003eFor audio, ESP-VoCat has a built-in 3W speaker and dual microphone array, supporting local voice wake-up and sound source localization. The power system is compatible with 5 V DC and 3.7 V lithium battery power supply. Additionally, it integrates a USB-C interface for power supply and programming download, while reserving a Pogopin interface for convenient functional expansion.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E01033-show1.jpg?v=1779418821\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E01033-show2.jpg?v=1779418850\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E01033-show3.jpg?v=1779418876\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E01033-show7.jpg?v=1779418936\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe following introduces the main components on the front PCB in clockwise order.
