  • Capacitive touch panel made of tempered glass with 6H hardness (case version only).
  • Interfaces: HDMI input, USB for touch, 3.5mm jack for HDMI audio output, optional VGA input (separate cable required).
  • Multi-language OSD menu for power management, brightness, and contrast adjustment.
  • Usable with Raspberry Pi under Raspberry Pi OS, Ubuntu, Kali, and RetroPie; the resolution must be set manually in config.txt.
  • Under Windows 11/10/8.1/8/7, touch is automatically detected after USB connection; with multiple monitors, touch defaults to the main screen.
  • When using multiple displays simultaneously, the touch can be assigned to a chosen monitor via xinput commands.
  • Power consumption is approximately 750–850 mA at 5 V input.
  • Case version offers adjustable tilt angles of 30°/50°.
  • Overall thickness of the display including PCB is about 6.88 mm; with the HDMI connector it is about 13.8 mm.

Notes and version constraints

  • With the Bullseye branch of Raspberry Pi OS, the KMS driver must be replaced by FKMS (dtoverlay=vc4-fkms-v3d); for CSI cameras, the Raspicam library must additionally be installed.
  • With multiple displays, touch defaults to the main screen; assigning it to a secondary screen requires manual configuration.
  • Some PCs do not support HDMI hot-plug; restarting the PC may resolve the issue.
  • Display flickering can be caused by insufficient USB power supply; connect an external power supply (5 V/2 A) to the DC port if needed.
  • The mini-HDMI-to-VGA cable must be purchased separately when using VGA signals.
  • PWM control of the backlight requires soldering a pad and removing a resistor; the exact implementation depends on the hardware revision and should be verified beforehand.
  • Exact mounting hole specifications for the enclosure are not provided in the source; this information must be confirmed by the manufacturer.
