ESP32 | AI Chatbot Breadboard DIY Electronic Kit with 128×64 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), 128×64 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.
