User Guide

Working with Raspberry Pi

Hardware Connection

1. Connect the TOUCH interface of the LCD to the USB connector of the Raspberry Pi.
2. Connect the LCD to the Raspberry Pi through the HDMI interface.

Software Setting

For Raspberry Pi OS/Ubuntu/Kali and Retropie system:

• 1. Insert the TF card into the PC, download and use Raspberry Pi Imager to program the corresponding image.

• 2. After programming the image, open the "config.txt" file located in the root directory of the TF card. Add the following code at the end of config.txt, save the file, and safely eject the TF card.

hdmi_group=2
hdmi_mode=87
hdmi_force_hotplug=1
hdmi_timings=720 0 40 40 200 720 0 24 4 12 0 0 0 78 0 59400000 0

• 3. Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds. After the system boots up, you should be able to enter the display interface and the LCD should touch normally.

Due to the round screen feature, it is recommended to use it with the Raspberry Pi remote login tutorial for boot setup.
