This DSI flat flex cable allows you to connect the Official Raspberry Pi Touchscreen Display to the Compute Module 4 IO Board (or other CM4 IO boards with a 22-pin 0.5mm pitch connector).
The cable has a 15-pin 1mm pitch connection on one side (for the touchscreen side) and a 0.5mm pitch 22-pin connection on the other (for the IO board). Both sides of the cable include black EMI shielding to reduce interference.
The cable is 15cm long.
