Hardware: PaperDIY, PC with Arduino IDE or M5Burner. 2. Install CP210x driver if needed for serial communication. 3. Open IDE, select 'M5Stack-ESP32-S3' board and the corresponding COM port. 4. Upload the 'WiFiScan' example or simple code using WiFi.h library. 5. Modify SSID and PASSWORD variables with your WiFi credentials (802.11b/g/n only, no 5GHz). 6. Upload code. Open Serial Monitor at 115200 baud. 7. You should see available networks then a 'Connected' message with an IP address. The ESP32-S3 module uses its integrated antenna. 8. Verify stability by pinging the IP address. 9. To go deeper, test station mode to fetch weather data.
