A developer-ready ESP32-S3 platform for LLM-powered voice interaction on the edge.
Built for toys, smart speakers, smart control hubs, and any voice-interaction product that needs large language models. Powered by the ESP32-S3-WROOM-1 module with a 1.85-inch QSPI round touchscreen and a dual-microphone array, it supports offline wake-word detection and sound-source localization — a solid foundation for developers building complete on-device AI experiences.
Seven capabilities that turn a reference design into a personality-rich companion
Proactively detects user intent and shifting emotions. Drawing on LLM semantic understanding, it interprets tone, word meaning and context together, then responds with lifelike expressions and voice — giving the device real personality.
Continuously records multi-turn conversations, remembering the user's name, preferences and frequent phrases, then recalls them later — a personalized experience that adapts to each user's habits.
A motor-control module paired with the dual-mic array tracks direction across a 180° range. Every call identifies the sound source and rotates the base to make eye contact.
Switch tones and styles freely to build your own signature AI voice identity. DIY voice persona support makes the voice experience more open and personal.
Supports the MCP protocol and Function Call to connect local smart devices for remote control, task dispatch and status feedback — a local control hub within a smart-home system.
Deeply integrated with leading LLM platforms — Amazon Nova, OpenAI, XiaoZhi AI and Gemini — giving developers flexible choices.
Combines voice and touchscreen interaction, and senses device posture changes through an IMU sensor for richer, more varied ways to engage.
