Please download the latest version of the image from the Raspberry Pi official website.
1. Download the compressed file to the PC, and extract the img file.
2. Connect the TF card to the PC and use SDFormatter to format the TF card.
3. Open the Win32DiskImager software, select the system image prepared in step 1, and click write to burn the system image.
4. After the programming is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt and save it. Save and safely eject the TF card, and insert the TF card into the Raspberry Pi.

5. Fasten the LCD to the Raspberry Pi through copper posts. At this time, the 5V and GND of the LCD will be connected to the corresponding GPIO of the Raspberry Pi through the pogo pin for the power supply.
6. After providing 12V for the LCD, you can see that the Raspberry Pi indicator and the LCD backlight light are on. After waiting for a few seconds, you can enter the system screen normally.
Working with PC
Support PC version Windows 11/10/8.1/8/7 system.
1) Connect the 12V power supply to the DC interface of the LCD, and you can see that the LCD backlight is on normally.
2) Connect the TOUCH interface of the LCD to the USB of the PC. After a while, Windows will automatically recognize the touch function.
3) Connect the HDMI interfaces between the LCD and the PC, please wait for a few seconds and you can see the LCD display normally.
- 1) When the PC is connected to multiple monitors at the same time, the touch effect works on the main screen by default. If you need to specify the touch to the other screen, see #Calibrate Touch on Win 10 PC.
- 2) Some PCs do not support plug-and-play with HDMI devices. Generally, they can be used normally after restarting the system.
Calibrate Touch on Win 10 PC
Take the windows10 system as an example:
- 1. Enter the Windows settings of the system, type in the search bar and click "Calibrate the screen for pen or touch input" (as shown in the picture below)
- 2. Click "Setup" in the pop-up "Tablet PC Settings" interface:
