Keyestudio Xiao Zhi AI Chatbot Breadboard DIY Electronic Kit with 128x64 OLED Screen Al Voice Assistant Starter Kit

Introduction

This is a DIY kit that allows you to quickly build a prototype of the “Xiao Zhi AI Chatbot” on a breadboard using simple hardware and speech recognition technology. It includes key components such as the ESP32-S3-DevKitC-1 development board, MEMS digital microphone (INMP441), digital amplifier (MAX98357A), 128x64 OLED screen, and cavity speaker, which support voice input and playback. There are reserved interfaces for further expansion, enabling basic human-machine interaction functionality.

Features

• Easy Setup, Quick to Get Started: All components can be plugged into the breadboard without complex soldering skills.

• Voice Input: Built-in MEMS digital microphone (INMP441) effectively reduces environmental noise interference.

• Audio Output: The combination of the digital amplifier (MAX98357A) and cavity speaker provides clear speech playback.

• Expandable: Extra GPIO and I²C interfaces are reserved for easily adding more sensors or functional modules to the robot.

• Learning-Friendly: Hands-on building and debugging allow users to gain a deeper understanding of the basic principles of AI voice recognition and playback.
