명세서

설정

1. 전원 공급 장치: Connect the development board to a 5V power source using the provided TYPE-C USB cable. You can connect it to a computer's USB port or a compatible USB power adapter.
2. 드라이버 설치: Depending on your operating system, you may need to install USB-to-serial drivers (e.g., CP210x or CH340G drivers) for your computer to recognize the ESP32 board. Refer to the ESP32 documentation for specific driver requirements.
3. 개발 환경 설정:
   • Install your preferred Integrated Development Environment (IDE), such as Arduino IDE, PlatformIO, or Espressif IDF.
   • Configure the IDE to support ESP32 development boards. This typically involves installing the ESP32 board package.
   • For graphical user interface (GUI) development, consider setting up LVGL.
4. 초기 프로그램 업로드:
   • Connect the board to your computer via the TYPE-C USB cable.
   • IDE에서 올바른 보드와 COM 포트를 선택하십시오.
   • 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.
5. Micro-TF Card (Optional): Insert a Micro-TF card into the designated slot for additional storage if your application requires it.
6. 외부 스피커(선택 사항): Connect an external speaker to the Horn interface if audio output is needed.
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.

작동 지침

1. 기본 작업: 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. 터치스크린 상호작용: 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.
   • 원하는 IDE(예: Arduino IDE)를 엽니다.
   • 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 인터페이스.
5. 오디오 재생: 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.

유지

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