Key Features
Expressive AI Companion
StackChan comes pre-loaded with the XiaoZhi AI agent, featuring animated facial expressions, voice interaction via dual microphones, and head movement driven by two feedback servos. It responds to voice commands, tells jokes, and acts as a desktop companion.
Fully Open Source
Every layer is open — hardware schematics, firmware, and 3D-printable shell designs are all available on GitHub. The maker community has already created hundreds of custom shells, behaviors, and integrations.
M5Stack Ecosystem Integration
Built on the CoreS3, StackChan is compatible with the entire M5Stack accessory ecosystem including Grove sensors, displays, and expansion modules. This makes it a powerful platform for IoT experimentation.
Multi-Platform Development
Program StackChan using Arduino IDE for direct C++ control, UiFlow2 for visual block programming, PlatformIO for professional development, or ESP-IDF for bare-metal access.
