Every time someone posts on the Adafruit forums and says they need to have a really long cable for their Pi Camera (CSI) or Pi Display (DSI), we say, "Oh you mean like some sort of CSI/DSI cable extender thingy? Yeah we don't have one of those in stock yet" But that time is over! Now we can say, "Yes we have a CSI/DSI Cable Extender Thingy in stock!" And we point them here.
