  • Compatible boards: Raspberry Pi 5, 4B, CM4, 3B+, 3A+, 3B, CM3, CM3+, 2B, B+, A+
  • Alternative boards: VisionFive 2 (Debian, single-point touch), Tinker Board 2 (Linux/Android, five-point touch), Core3566 (Debian/Ubuntu, five-point touch)

  • Backlight adjustment via terminal at /sys/class/backlight/*/brightness (range 0–255)
  • Display rotation via cmdline.txt or GUI depending on system version
  • Pre-installed Waveshare images are available; SDFormatter and Win32DiskImager recommended for flashing

Commands and examples – verify before use:  

dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch
dtoverlay=vc4-kms-dsi-7inch,dsi0
video=DSI-1:800x480M@60,rotate=90
echo X | sudo tee /sys/class/backlight/*/brightness
display_rotate=1

Notes and version constraints

  • Exact configuration lines depend on the system version (Trixie, Bookworm, Bullseye/Buster, Stretch/Jessie); select the procedure matching your specific image.
  • When using the DSI0 port, additionally set “dtoverlay=vc4-kms-dsi-7inch,dsi0” – only valid on Pi 5/CM4.
  • For Bookworm on Pi 5, it is recommended to manually update the system before first boot (“sudo apt-get update && sudo apt-get full-upgrade -y”).
  • On older systems (Bullseye/Buster), display and touch rotation must be configured separately.
  • The standoffs use M2.5 screws; verify fit and assembly before mounting.
