Project Purpose

This is an open-source project released under the MIT license, allowing anyone to use it freely, including for commercial purposes.

Through this project, we aim to help more people get started with AI hardware development and understand how to implement rapidly evolving large language models in actual hardware devices. Whether you're a student interested in AI or a developer exploring new technologies, this project offers valuable learning experiences.

Everyone is welcome to participate in the project's development and improvement. If you have any ideas or suggestions, please feel free to raise an Issue or join the chat group.

Firmware Section

Flashing Without Development Environment

For beginners, it's recommended to first use the firmware that can be flashed without setting up a development environment.

The firmware connects to the official xiaozhi.me server by default. Currently, personal users can register an account to use the Qwen real-time model for free.

👉 Flash Firmware Guide (No IDF Environment)

Development Environment

• Cursor or VSCode
• Install ESP-IDF plugin, select SDK version 5.3 or above
• Linux is preferred over Windows for faster compilation and fewer driver issues
• Use Google C++ code style, ensure compliance when submitting code

Developer Documentation

• Board Customization Guide - Learn how to create custom board adaptations for XiaoZhi
• IoT Control Module - Understand how to control IoT devices through AI voice commands

AI Agent Configuration

If you already have a XiaoZhi AI chatbot device, you can configure it through the xiaozhi.me console.
