Featured Design

  1. LCD FFC cable anti-interference design, more stable for industrial applications.
  2. VCOM voltage adjustment for optimizing display effect.
  3. Power supply via pogo pins, eliminating messy cables connection.
  4. Two types of 5V output headers, for connecting cooling fans or other low-power devices.
  5. Reversed the camera hole on the touch panel for the external camera.
  6. Large front panel design, makes it easy to match user-defined cases or to be integrated into sorts of devices.
  7. Adopts SMD nuts for holding and fixing the board, a more compact structure.

Hardware connection

Working with Pi 4B/3B+/3A+/3B/2B/B+/A+

1) Use the 15PIN FPC cable to connect the DSI interface of the 8-inch DSI LCD to the DSI interface of Raspberry Pi.
2) For ease of use, you can attach the Raspberry Pi to the back of the 8-inch DSI LCD fixed with screws, and assemble the copper pillars. (The Raspberry Pi GPIO interface will power the LCD through the Pogo pin).
The connection is as below:

Working with Pi 5/CM4/CM3+/CM3

1. Connect the 8inch DSI LCD to the 22PIN DSI1 connector on the Raspberry Pi board using the DSI-Cable-12cm cable.
2. Connect the LCD's power connector to the Raspberry Pi's 40PIN GPIO header using the 2PIN power connector cable.
3. For ease of use, the Raspberry Pi 5 can be screwed to the back of the 8-inch DSI LCD and assembled with copper posts. As shown in the figure below:

Software Settings

Raspberry Pi OS Imager Insallation

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

  • 1. Connect the TF card to the PC, download and use Raspberry Pi Imager to program the corresponding system.

  • 2. After installing the imager, open the "config.txt" file on the TF card root directory, add the following codes at the end of "config.txt", and then safely remove the TF card.
Note: as there are two MIPI DSI interfaces on the Pi5/CM4/CM3+/CM3, please pay attention to using the correct DSI interface and commands, and the DSI1 interface is recommended. 
dtoverlay=vc4-kms-v3d
#DSI1 Use
dtoverlay=vc4-kms-dsi-7inch
#DSI0 Use
#dtoverlay=vc4-kms-dsi-7inch,dsi0
  • 3. Insert the TF card into the Raspberry Pi, power it up, and wait for a few seconds for the display. Once the system boots up, you should be able to interact with it normally, including touchscreen functionality.

Backlight Control

WaveShare provides the corresponding demo for the application (only supports Bookworm and Bullseye systems). Users can install it by the following commands:

wget https://www.waveshare.com/w/upload/f/f4/Brightness.zip
unzip Brightness.zip
cd Brightness
sudo chmod +x install.sh
./install.sh

After installation, you can open it: Menu -》Accessories -》Brightness:

43H-800480-IPS07.GIF

In addition, you can also input the following commands to control the backlight brightness:

echo X | sudo tee /sys/class/backlight/*/brightness

Where X indicates any number from 0 to 255. 0 means the backlight is the darkest, and 255 means the backlight is the brightest. For example:

echo 100 | sudo tee /sys/class/backlight/*/brightness
echo 0 | sudo tee /sys/class/backlight/*/brightness
echo 255 | sudo tee /sys/class/backlight/*/brightness

Sleep

Run the following commands on the Raspberry Pi terminal, and the screen will enter sleep mode:

xset dpms force off

The above command is only for Bullseye and Buster systems.

Disable Touching

If you want to disable the touch function, you can modify the config.txt file, add the following line to the file and reboot the system. (The config file is located in the root directory of the TF card, and can also be accessed through the command: sudo nano /boot/config.txt):

disable_touchscreen=1

Note: After adding the command, it needs to be restarted to take effect.

 Answer:

This screen currently only supports Raspberry Pi and the official OS of Raspberry Pi. For OrangePi (Rockchip RK3566), we have no driver support for the time being.
It is recommended that you use our driver-free DSI screen, such as an 8-inch DSI LCD, we can provide the RK3288 demo that lights up the screen for you to transplant.
