1. Prepare the Raspberry Pi: Ensure your Raspberry Pi 4 Model B board is ready.
2. Mount the Raspberry Pi: Attach the Raspberry Pi 4 board to the designated mounting points on the back panel of the acrylic case using the provided screws and standoffs.
3. Дэлгэцийг холбоно уу: Connect the 7-inch LCD to the Raspberry Pi 4. Typically, this involves connecting the HDMI cable from the display to one of the micro-HDMI ports on the Raspberry Pi, and the USB-A to Micro-USB cable for touch functionality and power.
4. Assemble the Case: Secure the front panel of the acrylic case around the display and then attach it to the back panel, enclosing the Raspberry Pi and display. Ensure all cables are properly routed and not pinched.
5. Суурилуулалтын суурь: Assemble and attach the included stand to the bottom of the case for stable positioning. The stand often allows for adjustable viewing angles (e.g., 45° or 60°).

4.2 Програм хангамжийн тохиргоо

The Waveshare 7-inch capacitive touch LCD is designed for driver-free operation with several popular operating systems.

1. Үйлдлийн системийн суурилуулалт: Install your preferred operating system (e.g., Raspbian, Ubuntu, Kali, WIN10 IoT, Retropie) onto the provided 16GB Micro SD card using a suitable imaging tool (e.g., Raspberry Pi Imager).
2. SD карт оруулах: Insert the prepared Micro SD card into the Raspberry Pi's Micro SD card slot.
3. Асаах: Connect the power adapter to the display kit. The Raspberry Pi and display should power on automatically.
4. Жолоочгүй ажиллагаа: For most supported systems, the display and touch functionality will work automatically without additional driver installation.
