AtomS3R AI Chatbot Kit (8MB PSRAM)

The AtomS3R-AI Chatbot kit combines an ESP32-S3 controller with 8MB Flash, 8MB PSRAM, 9-axis IMU, and an IR emitter, with a voice base featuring the ES8311 audio codec for high-quality audio. It supports multiple voice assistants for real-time interaction

M5Stack AtomS3R-AI Chatbot is an AI voice development kit. The kit consists of two core parts: the controller and the voice base. The controller adopts AtomS3R, which is based on the ESP32-S3 chip. It provides a large memory combination of 8 MB Flash + 8 MB PSRAM.

It also integrates a 9-axis IMU (BMI270 + BMM150), IR emission tube, and other rich peripherals. The voice base uses 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, enabling real-time voice interaction, custom wake words, and low-latency recognition.
