On the Raspberry Pi there are two components about an inch long, one next to the ethernet and one next to the logo. I have been wondering since I received the device what these components are?
These are the components I'm referring to.
According to this diagram, they are your CSI and DSI connectors, for camera and display, respectively.
Camera & display ribbon cable slots. FYI the display ribbon cable slots in correctly only one way. The camera connection will accept the ribbon cable either way!
