This cable will let you swap out the stock 150mm long flex cable from a Raspberry Pi Camera for a different size. Works great, just carefully open the connector on the Pi and slip this one in. This cable is 2 meters long. Please note, Adafruit did test this length cable with their Pi Model B/B and a Pi Camera and it worked great but 2 meters is really long for this kind of camera protocol, so if you have a very electrically noisy environment (inside a tesla coil?) you may have corrupted images.
