Инструкции по установке
Follow these steps to assemble and set up your display kit:
- Подготовьте Raspberry Pi: Insert the provided MicroSD card into the Raspberry Pi 4 Model B.
- Установите Raspberry Pi: Secure the Raspberry Pi 4 to the back of the 7-inch LCD display using the provided standoffs and screws. Ensure proper alignment with the display's connectors.
- Подключите кабели дисплея:
- Connect one end of the Micro HDMI cable to the Raspberry Pi's Micro HDMI port and the other end to the display's HDMI input.
- Connect the USB-A to Micro USB cable from a USB 2.0 port on the Raspberry Pi to the Micro USB port on the display. This provides power for the display's backlight and enables touch functionality.
- Assemble the Acrylic Case: Carefully attach the acrylic case components around the assembled display and Raspberry Pi. Refer to the case assembly diagram for correct orientation.
- Подключите питание: Plug the USB power adapter into a wall outlet and connect the USB-A to USB-C cable to the Raspberry Pi's USB-C power input.
- Первоначальная загрузка: The system should power on automatically. The display will show the boot sequence.

Операция
Once the display kit is powered on, the pre-installed operating system (typically Raspbian) will boot. You can interact with the system using the capacitive touch screen.
- Сенсорная функциональность: The 7-inch display supports up to five-point capacitive touch when running Raspbian. For other supported operating systems like Ubuntu, Kali, or WIN10 IoT, it typically supports single-point touch.
- Подключение периферийных устройств: Use the USB ports on the Raspberry Pi to connect a keyboard, mouse, or other USB devices as needed.
- Сетевое подключение: The Raspberry Pi 4 supports Gigabit Ethernet and 2.4/5GHz Wi-Fi for internet access.
- Аудиовыход: Audio can be output via the 3.5mm audio jack or HDMI.

- Обновления программного обеспечения: Regularly update the operating system and installed software on your Raspberry Pi to ensure optimal performance and security.
- Условия окружающей среды: Operate the device in a clean, dry environment. Avoid extreme temperatures, direct sunlight, and high humidity.
- Управление энергопотреблением: Always shut down the Raspberry Pi gracefully through the operating system before disconnecting power to prevent data corruption.
Поиск неисправностей
- Нет изображения на экране:
- Ensure the Micro HDMI cable is securely connected to both the Raspberry Pi and the display.
- Verify the Raspberry Pi is receiving power (check the power LED on the Pi).
- Confirm the MicroSD card is properly inserted and contains a valid operating system image.
- Touch screen not responding:
- Check that the USB-A to Micro USB cable is connected from the Raspberry Pi to the display.
- Ensure the operating system supports touch functionality and that necessary drivers (if any, though typically driver-free for supported OS) are loaded.
- Перезагрузите Raspberry Pi.
- Система не загружается:
- Confirm the power supply is adequate (5V/3A recommended for Raspberry Pi 4).
- Re-flash the operating system image onto the MicroSD card.
