સેટઅપ સૂચનાઓ
Follow these steps to assemble and set up your display kit:
- રાસ્પબેરી પાઇ તૈયાર કરો: Insert the provided MicroSD card into the Raspberry Pi 4 Model B.
- રાસ્પબેરી પાઇ માઉન્ટ કરો: 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.
- ડિસ્પ્લે કેબલ્સ કનેક્ટ કરો:
- 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.
- પાવર કનેક્ટ કરો: 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.
- પ્રારંભિક બુટ: The system should power on automatically. The display will show the boot sequence.

ઓપરેશન
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.
- ટચ કાર્યક્ષમતા: 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.
- કનેક્ટિંગ પેરિફેરલ્સ: Use the USB ports on the Raspberry Pi to connect a keyboard, mouse, or other USB devices as needed.
- નેટવર્ક કનેક્ટિવિટી: The Raspberry Pi 4 supports Gigabit Ethernet and 2.4/5GHz Wi-Fi for internet access.
- ઓડિયો આઉટપુટ: Audio can be output via the 3.5mm audio jack or HDMI.
