M5Stack AtomS3R AI Chatbot + Echo Base

The M5Stack AtomS3R AI Chatbot Kit combines the compact AtomS3R controller with the powerful Echo Base, making it ideal for voice-based edge-AI projects. At its core is an ESP32-S3-PICO-1-N8R8 dual-core microcontroller with 8 MB Flash and 8 MB PSRAM, supporting local voice inference and Wi-Fi connectivity. The Echo Base features an ES8311 audio codec, dual MEMS microphones, and an integrated Class-D speaker, enabling clear full-duplex voice interactions. An integrated 9-axis sensor (BMI270 + BMM150) allows for precise movement and position detection. Power is supplied via USB-C, while the modular design ensures full compatibility with additional ATOM extensions. The kit is suitable for use with open-source voice assistants, learning systems, or smart home controls. Thanks to support for ESP-IDF, Arduino, PlatformIO, and UiFlow2, it can be quickly integrated into existing development environments. Ideal for DIY projects, research, education, and voice control in IoT.
