DESCRIPTION
The Xiaozhi AI Kit with ESP32-S3 is a powerful, feature-rich development board designed for AI and IoT applications. Built around the ESP32-S3 chip, this kit delivers high-performance edge AI computing with dual-core processing, Wi-Fi & Bluetooth 5 (BLE) connectivity, and extensive GPIO support—perfect for machine learning (ML), computer vision, voice recognition, and smart device prototyping.
This is an open-source ESP32 project, released under the MIT license, allowing anyone to use it for free, including for commercial purposes.
As a voice interaction entry, the XiaoZhi AI chatbot leverages the AI capabilities of large models like Qwen / DeepSeek, and achieves multi-terminal control via the MCP protocol.
For beginners, it is recommended to use the firmware that can be flashed without setting up a development environment.
The firmware connects to the official xiaozhi.me server by default. Personal users can register an account to use the Qwen real-time model for free.
