AtomS3R-M12 Volcengine Kit

SKU:D062-M12

Description

AtomS3R‑M12 Volcengine Kit is an IoT vision+voice development kit that deeply integrates M5Stack hardware with Volcengine’s cloud AIGC one-stop solution. It consists of two core parts: the high-performance image capture unit AtomS3R‑M12 and the AI voice processing base Atomic Echo Base. AtomS3R‑M12 provides 3 MP wide-angle video capture and edge computing capabilities, with expansion interfaces for various sensors. Atomic Echo Base integrates high-fidelity audio decoding, microphone, and speaker drivers, supporting full-duplex voice wake-up, recognition, and interaction. Volcengine RTC, in collaboration with M5Stack, offers a built-in one-stop solution that integrates advanced audio processing (including wake‑up and audio 3A) on the chip side, and deeply incorporates large models, speech recognition, speech synthesis, function calling, and knowledge-base technologies on the cloud side, quickly achieving smooth, natural, human-like real-time communication between users and hardware. It is widely applied in smart security, remote education, smart home, industrial monitoring, AI robotics, and other fields.
