Инструкции за настройка
Follow these steps to assemble and set up your display kit:
- Подгответе Raspberry Pi: Insert the provided MicroSD card into the Raspberry Pi 4 Model B.
- Монтиране на 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.
- Свържете кабелите на 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.
- Свържете захранването: 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.
- Първоначално зареждане: The system should power on automatically. The display will show the boot sequence.
