Techopedia explains Lightning Connector. The Lightning connector was a successor to the previously used 30-pin connector. It is a small wire with a USB 2.0 interface at one end and a connector plug at the other. The connector consists of a communication bus for dual data transfer; it also provides electrical power to the device.
Using eight pins instead of thirty, Lightning is significantly more compact than the 30-pin dock connector and can be inserted with either side facing up. However, it is incompatible with cables and peripherals designed for its predecessor, unless used with an adapter.pple offers various adapters which allow the Lightning connector to be used with other interfaces, such as 30-pin, USB, HDMI, VGA, and SD cards. The Lightning to 30-pin adapter supports only a limited subset of the available 30-pin signals: USB data, USB charging, and analog audio output.
