What do you want to join?
Want to connect your iPhone to a television or an external monitor? You can. Which converter you need depends on the connection of your external screen. Options include VGA and HDMI converters. Most televisions now have HDMI ports. Because iPhone doesn't have a HDMI connector, you need a special HDMI adapter. The converter you need also depends on your iPhone. Do you have an old iPhone with 30-pin connection or a later model (from iPhone 5) with a Lightning connector? Other than the adapter, you also need an HDMI cable to connect the screen.
Connect SD card
