K147

K147 is an AtomS3R AI Chatbot Kit (8MB PSRAM) which 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 8MB Flash + 8MB 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 Voice 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. Suitable for smart home and voice assistance applications.
