Opsætningsinstruktioner

Follow these steps to assemble and set up your display kit:

1. Prepare the Raspberry Pi: Insert the provided MicroSD card into the Raspberry Pi 4 Model B.
2. Mount the 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.
3. Connect Display Cables:
   • 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.
4. 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.
5. Tilslut strøm: 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.

Fejlfinding

Ingen displayudgang:

• 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.
• Restart the Raspberry Pi.

System not booting:

• Confirm the power supply is adequate (5V/3A recommended for Raspberry Pi 4).
