Hiwonder ESP32-S3 Development Board AI Vision & Smart Chat with LLMs Robot Programming Board Kit

The Hiwonder ESP32-S3 Development Board is a powerful, multimodal AI robotics controller designed for students, educators, and makers looking to explore advanced artificial intelligence. Integrating text, voice, and vision engines, this versatile board supports popular large language models like DeepSeek and Qwen3 alongside offline vision processing. It is the ideal hardware platform for building smart interactive companions, environmental monitoring systems, and vision-guided robotics.

Multimodal AI model deployment

The board deeply integrates text, voice, and vision models to enable smart chat interactions and advanced environmental perception. Users can switch between popular large language models such as DeepSeek, Qwen3, and DouBao to customise the AI's personality, tone, and knowledge base.

Personalised XiaoZhi AI integration

Compatibility with the XiaoZhi AI platform allows you to create custom characters with unique traits, voices, and background knowledge. With support for over 30 languages and dozens of voice options, you can craft highly personalised AI companions.

LVGL graphical user interface

The integrated LVGL interface provides real-time camera viewing and local media playback directly on an HD LCD touchscreen. It also allows developers to monitor and control servo parameters, temperature, lighting, and IMU data on the fly.

Offline AI vision interaction

By flashing the dedicated firmware, the board performs offline visual tasks without relying on cloud connectivity. This enables local colour recognition, face detection, object tracking, and visual line following.

High-performance ESP32-S3 chip

Powered by the low-power ESP32-S3 dual-mode chip, the board delivers 600 DMIPS of processing power. This provides a robust computing foundation for demanding DIY development and real-time robotics control.

Detachable high-definition camera

The included 2MP detachable camera captures 1080p video at 60 frames per second for high image clarity and colour accuracy. This high-performance sensor significantly improves the precision and stability of visual recognition tasks.

Noise-cancelling microphone for voice control

The onboard high-performance microphone is designed to filter out background noise for reliable voice capture. This ensures smooth, natural voice interactions and accurate command recognition in real-world settings.

High-fidelity speaker feedback

An integrated high-fidelity speaker unit provides clear, rich audio output for voice broadcasting and system notifications. This enables realistic audio feedback for interactive AI applications and smart assistant projects.
