27,80 €
TTC
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 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.
