AtomS3R-AI Chatbot
SKU:K147
Description
AtomS3R-AI Chatbot is an AI voice development kit consisting of two core parts: a controller and a voice base.
The controller adopts AtomS3R, which is powered by the ESP32-S3 chip and provides a generous 8 MB Flash + 8 MB PSRAM memory combo. It also integrates a 9-axis IMU (BMI270 + BMM150), an IR transmitter, and other rich peripherals.
The voice base is the Atomic Echo Base, built on the ES8311 audio codec, delivering high-fidelity audio decoding together with microphone and speaker driving capability.
The kit supports multiple voice assistants such as XiaoZhi Voice Assistant, OpenAI Voice Assistant, and Volcano Engine Voice Assistant, enabling real-time voice interaction, custom wake-words, and low-latency recognition.
