Description AtomS3R-CAM AI Chatbot Kit is an AI vision and voice development kit that combines an AtomS3R-CAM controller with an Atomic Voice Base. The controller is built around the ESP32-S3-PICO-1-N8R8 platform with 8MB Flash, 8MB PSRAM, a 0.3MP GC0308 camera, a 9-axis sensor system, an IR emitter, bottom GPIO, and a HY2.0-4P expansion port. The Atomic Voice Base adds an ES8311 24-bit audio codec, MEMS digital microphone, Class-D amplifier, and 8 ohm 1W speaker for full-duplex I2S voice interaction. Together, the AtomS3R-CAM AI Chatbot Kit supports XiaoZhi Voice Assistant, OpenAI Voice Assistant, and Volcengine Voice Assistant workflows for compact AI assistant and smart home projects. For embedded developers, the kit brings camera input, microphone input, speaker output, Wi-Fi connectivity, IMU sensing, and firmware workflows through ESP-IDF, PlatformIO, Arduino, UiFlow2, and M5Burner. Note: Products with magnets may interfere with the BMM150 magnetic field sensor and cause abnormal readings. When used with an M5 controller that contains a magnet, remove the magnet and keep the BMM150 sensor away from strong magnetic fields.

The AtomS3R-CAM AI Chatbot Kit package includes one AtomS3R-CAM controller and one Atomic Voice Base. What makes this version different from a voice-only assistant kit? This version adds a 0.3MP GC0308 camera to the controller, so it can support compact AI assistant projects that need both vision input and voice interaction. Which assistant workflows are supported? The kit is designed around XiaoZhi Voice Assistant, OpenAI Voice Assistant, and Volcengine Voice Assistant workflows documented for AtomS3 series devices with Atomic Voice Base. What should be considered around magnets? Magnets may interfere with the BMM150 magnetic field sensor. Keep the sensor away from strong magnetic fields and remove nearby magnets when needed.
