AtomS3R-CAM AI Chatbot Kit (8MB PSRAM)

The AtomS3R-CAM AI Chatbot kit combines an ESP32-S3 controller with 8MB Flash, 8MB PSRAM, a 0.3MP camera, 9-axis IMU, IR emitter, and a voice base with ES8311 audio codec, supporting multiple voice assistant integrations.

M5 Stack AtomS3R-CAM AI Chatbot kit is an AI vision and voice development kit. The kit consists of two core parts: the controller and the voice base. The controller uses AtomS3R-CAM, which is built around the ESP32-S3 chip.

It provides a large memory combination of 8MB Flash + 8MB PSRAM. It also integrates a 0.3MP GC0308 camera, a 9-axis IMU (BMI270 + BMM150), an IR emitter tube, and other rich peripherals. The voice base uses the Atomic Echo Base, based on the ES8311 audio codec chip, capable of high-fidelity audio decoding and microphone and speaker driving. The kit supports integration with XiaoZhi Voice Assistant, OpenAI Voice Assistant, and Volcengine Voice Assistant, making it suitable for voice assistant, smart home, and other embedded scenarios.

USB-C cable required but not included.
