Keyestudio Ready‑to‑Use ESP32‑S3‑Mini XiaoZhi AI Chatbot DIY Kit (Basic Version with 1.54‑inch LCD Screen)

Introduction

Based on modular hardware and local speech recognition technology, this kit builds the “XiaoZhi AI Chatbot” interactive solution. It is equipped with an ESP32‑S3 main controller, camera, MEMS digital microphone (ICS‑43432), digital power amplifier (NS4168), 1.54‑inch color LCD screen and loudspeaker. It supports voice input and real‑time audio broadcast, and adds visual recognition capability for richer AI interaction experiences. A battery holder and USB cable are included. It can run immediately with external USB power, and supports portable operation with batteries installed.

Features

Vision Enhancement: Integrated camera module gives the robot “eyes” for image recognition, monitoring and other scenarios.
High‑Integration, Ready‑to‑Run: Mainboard, expansion board and functional modules are pre‑mounted on an acrylic frame. Simple wiring completes assembly; no soldering or breadboard jumper wires required.
Voice Input: Built‑in MEMS digital microphone (ICS‑43432) effectively suppresses ambient noise.
Audio Output: Digital power amplifier (NS4168) plus enclosed loudspeaker delivers clear voice playback.
Expandable: The expansion board exposes extra GPIO, I²C and other interfaces via 2.54mm pin headers for connecting additional sensors and modules.
Portable: Supports battery‑holder power supply (6‑9 V) for untethered mobile use.
Education‑Friendly: Hands‑on assembly and debugging help users understand basic principles of AI speech recognition and audio playback.
