Mobile Apple devices that were released before the iPod Nano (seventh generation), iPod Touch (fifth generation), iPhone 5, iPad Mini and fourth-generation iPad, use Apple's 30-pin connector. There are different types of 30-pin adapters available that allow you to transport all kinds of signals.
In addition to the well-known Camera Connection Kit, we also stock 30-pin to USB adapters, 30-pin to MIDI adapters and 30-pin to VGA adapters. The new standard is Lightning, which means that if you want to connect a 30-pin device to an Apple device with Lighting, your should use a Lightning adapter that has a Lightning to 30-pin connector.
