The Raspberry Pi Camera Module comes fully assembled with a 15-Way 150mm flat, flex cable that plugs directly in the Raspberry Pi CSI port. Unfortunately the included cable is quite fragile, and can break if twisted or bent too far.
Don't worry though, not all is lost if that cable does happen to break! Replacement raspberry pi camera board cables are available from ModMyPi, and it's very easy to swap them over!
This replacement cable is 100mm long.
