I recently was asked a question concerning the contents of the 7" LCD touch screen kit for Raspberry Pi (Digi-key part number 1690-1007-ND) Raspberry PI part number 8997466.
The kit contains the following items:
- 7” Touchscreen Display
- Adapter Board
- DSI Ribbon cable
- 4 x stand-offs and screws (used to mount the adapter board and Raspberry Pi board to the back of the display)
- 4 x jumper wires (used to connect the power from the Adapter Board and the GPIO pins on the Pi so the 2Amp power is shared across both units)
The 800 x 480 display connects via an adapter board that handles power and signal conversion.
