This 7″ Touchscreen Display for the Raspberry Pi is perfect for creating portable and embedded projects where a keyboard and mouse would be in the way.
The full-color display outputs up to 800 x 480 and features a capacitive touch sensing capable of detecting 10 fingers.
Only two connections from the Pi to the display are necessary; power from GPIO (or USB) connection to the DSI port. The adapter board handles power, signal conversion, and touch input conversion.
Easy to install but problems getting official Pi product to fit the screen with Pi4. No matter what I did the right side of the screen is off the edge making it hard to make applications fit properly.
