7. External Battery (Optional): For portable applications, connect a 3.7V lithium polymer battery to the lithium battery interface. The board includes a charging management circuit.

Enstriksyon Operasyon

1. Operasyon debaz: Once powered, the display will activate according to the loaded firmware. If no program is loaded, it may show a default boot screen or remain blank.
2. Entèraksyon ekran taktil: Use the included stylus or your finger to interact with the touch display. The responsiveness and functionality depend on the application programmed onto the ESP32.
3. Programming and Firmware Upload:
   • Connect the board to your computer via the TYPE-C USB port.
   • Open your chosen IDE (e.g., Arduino IDE).
   • Write or load your program code.
   • Compile the code and upload it to the ESP32 board. Ensure the correct board and port are selected.
   • If the upload fails, try holding down the BOOT button while pressing and releasing the RESET button, then release BOOT, and attempt the upload again.
4. IoT Applications:
   • Utilize the integrated WiFi and Bluetooth for remote monitoring, control, and data exchange.
   • Develop applications for remote data query, environmental monitoring, and parameter adjustment via mobile apps or web interfaces.
5. Lektur odyo: If an external speaker is connected, the ESP32 can be programmed to play audio files or generate sounds.
6. RGB Indicator: Observe the three-color RGB LED for status indications as defined by your custom firmware.

Antretyen

• Netwayaj: Keep the board and display clean. Use a soft, dry cloth to wipe the screen. Avoid abrasive cleaners or solvents.
• Depo: Store the development board in a dry, anti-static environment when not in use. Avoid extreme temperatures and humidity.
