A 7" TFT display with 800×480 (WVGA) resolution and a compact HDMI mini driver board. Simply connect the USB power cable to a 5V supply and plug in an HDMI source for instant video output — no complex configuration required.
The display uses the AT070TN94 panel and is driven by a small HDMI driver board that fits neatly behind the screen. A wired button PCB provides access to an on-screen menu for adjusting brightness, colour, and contrast. The driver auto-detects the input source or can be manually selected via the menu keypad.

Note: Power adapter and stand are not included. Use a 500mA-capable 5V USB port, or cut the USB power cable and rewire to another 5V source. For Raspberry Pi, edit
config.txt to set the HDMI output to 800×480 if the resolution is not auto-detected. BeagleBone Black works without additional configuration.
Jargon buster
Plain-language definitions for the technical terms used above.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- TFT
- A thin-film transistor display is a common type of colour LCD used for graphics screens. Knowing a product is for TFTs helps you check that the driver board matches the display’s connector, resolution, backlight, and signalling method.

Example config.txt for using this display with Raspbery Pi
# uncomment if you get no picture on HDMI for a default "safe" mode #hdmi_safe=1 # uncomment this if your display has a black border of unused pixels visible # and your display can output without overscan #disable_overscan=1 # uncomment the following to adjust overscan. Use positive numbers if console # goes off screen, and negative if there is too much border #overscan_left=16 #overscan_right=16 #overscan_top=16 #overscan_bottom=16 # uncomment to force a console size. By default it will be display's size minus # overscan. #framebuffer_width=1280 #framebuffer_height=720 # uncomment if hdmi display is not detected and composite is being output hdmi_force_hotplug=1 # uncomment to force a specific HDMI mode (here we are forcing 800x480!) hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_cvt=800 480 60 6 0 0 0 # uncomment to force a HDMI mode rather than DVI. This can make audio work in # DMT (computer monitor) modes #hdmi_drive=2 # uncomment to increase signal to HDMI, if you have interference, blanking, or # no display #config_hdmi_boost=4 # uncomment for composite PAL #sdtv_mode=2 #uncomment to overclock the arm. 700 MHz is the default. #arm_freq=800 # for more options see http://elinux.org/RPi_config.txt
