🛠️ Quick‑Start Assembly & Usage Guide

1. Unbox & Layout

  • Place the two 400‑hole breadboards side by side.

  • Insert the ESP32‑S3 DevKit so its Type‑C port faces outward.

2. Wire the Modules

Follow the wiring diagram (based on the official docs) oshwlab.com+4docs.keyestudio.com+4docs.keyestudio.com+4 :

Microphone (I²S INMP441):

  • GPIO4 → WS

  • GPIO5 → SCK

  • GPIO6 → SD

  • 3V3 → VDD

  • GND → GND

Amplifier & Speaker (I²S MAX98357A):

  • GPIO7 → DIN

  • GPIO15 → BCLK

  • GPIO16 → LRC

  • 3V3 → VCC

  • GND → GND

  • Speaker → Audio+ / Audio−

OLED Display (I²C SSD1306):

  • GPIO41 → SDA

  • GPIO42 → SCL

  • 3V3 → VCC

  • GND → GND

Buttons:

  • Volume–: GPIO39 → button → GND

  • Volume+: GPIO40 → button → GND

  • Wake Button: GPIO0 → button → GND

🔧 Tips: Ensure all GND lines are common; double‑check each connection to avoid mismatches docs.keyestudio.com+2docs.keyestudio.com+2oshwlab.com+2 GitHub .

3. Flash the Firmware

  • Install Espressif’s Flash Download Tool.

  • Download the latest merged-binary for 128×64 OLED.

  • Connect the ESP32 via USB, select ESP32‑S3, set baud and port, and flash the .bin to address 0x0 docs.keyestudio.com+3docs.keyestudio.com+3docs.keyestudio.com+3 .

  • After flashing, press RST, and the onboard RGB LED will blink—indicating configuration mode is ready.

4. Wi‑Fi Configuration

5. Add Your Device to Keyestudio Cloud

6. Use & Expand

  • Wake with the button or voice, ask questions.

  • Volume up/down buttons adjust audio playback.

  • Expandable GPIO allow adding sensors (e.g., temperature, LED notifications).

  • Customize firmware or develop new features using Arduino IDE or ESP‑IDF.
