M5Stack AtomS3R AI Chatbot CAM + Echo Base

The M5Stack AtomS3R AI Chatbot Kit combines a powerful speech and camera unit (AtomS3R-CAM) with an audio base (Echo Base) into a complete solution for interactive edge AI applications. The integrated ESP32-S3-PICO-1-N8R8 dual-core microcontroller offers speech recognition (edge inference) as well as Wi-Fi connectivity. The camera (0.3 MP GC0308) and the IR emitter enable visual interaction even in darkness. The 9-axis sensor module (BMI270 + BMM150) provides accurate motion and magnetic field data. The Echo Base contains an ES8311 audio codec, class-D speaker, and dual microphones for full-duplex speech output. Designed for integration with voice assistants like XiaoZhi or OpenAI, the kit can be used as a smart home interface, portable voice assistant, or interactive EduBot. The modular design allows it to be combined with additional AtomS3R extensions. The kit is ideal for projects in education, smart home, robotics, and IoT.

Features:

The integrated ESP32-S3-PICO-1-N8R8 provides edge AI inference directly on the device.
The GC0308 camera captures video up to 30 fps with 0.3 MP resolution and FOV 57.6°.
The IR emitter enables detection and illumination in the dark up to 12.46 m.
The 9-axis sensor complex combines BMI270 and BMM150 for precise motion and magnetic field tracking.
The ES8311 audio codec offers 24-bit I²S audio quality and full-duplex voice operation.
Dual MEMs microphones (≥ 65 dB SNR) enable clear voice recordings and noise cancellation.
Class-D speakers (1 W, 8 Ω) deliver balanced sound in a compact size.
Compatible with ESP-IDF, Arduino, PlatformIO, and UiFlow2 for easy software integration.

Applications:

Implementation of a local voice input assistant with camera feedback.
Integration into smart home systems as a touch and camera interface.
Used as an interactive WAV bot or workshop teaching tool for AI speech technology.
Use as a portable edutainment device with IR communication.
Robot integration with environmental and motion sensors.
