Hardware Connection​

Using Raspberry Pi 5 as an example, prepare the display, Raspberry Pi board, power cable, HDMI cable, USB touch cable, and the corresponding adapters.

1. Connect the HDMI ribbon cable ①, the USB touch cable ②, and the power cable ③ to the corresponding interfaces on the screen baseboard. Confirm that the ribbon cable is fully inserted and the connector is locked.

   
   

2. Connect the other end of the HDMI ribbon cable ① to an adapter suitable for the mainboard. For the Raspberry Pi 5 / 4B, use the Micro HDMI adapter ⑤, and then connect it to the mainboard's Micro HDMI interface.

   
   

3. Connect the USB plug of the touch cable ② to the Raspberry Pi's USB interface. According to the positions in the figure, connect the two 5 V wires and the GND wire of the power cable ③ to the corresponding pin headers on the Raspberry Pi, verify the polarity, and then power on.

   
   

Software Setup​

1. Connect the TF card to the PC, download and use Raspberry Pi Imager to flash the latest Raspberry Pi OS.

   
   

2. After flashing, open the config.txt file in the root directory of the TF card, add the following configuration at the end of the file, save, and safely eject the TF card.

   max_framebuffer_width=1080
   max_framebuffer_height=1080
   hdmi_group=2
   hdmi_mode=87
   hdmi_timings=1080 0 40 8 132 1080 0 17 3 68 0 0 0 60 0 88000000 3
   

3. Insert the TF card into the Raspberry Pi and connect a 5 V power supply to the display. After the system boots, display and touch functions will work normally.

   
   

Due to the circular screen design, it is recommended to use the Raspberry Pi remote access tutorial for initial setup and configuration.

Hardware Connection​

1. Connect the Touch interface of the LCD to the USB interface of the PC, and Windows will automatically recognize the touch function.

2. Connect the HDMI interface of the LCD to the HDMI interface of the PC, and Windows will automatically recognize the display function.

   NOTE

   Some PCs do not support HDMI plug-and-play; a system restart usually resolves this.

   If the USB port cannot supply sufficient power, it may cause screen flickering. This can be resolved by connecting an external 5V 1A power adapter to the LCD's Power interface.
