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.
Apple's Thunderbolt connectors have a smaller sibling: Lightning, which replaces the familiar Dock connector on the iPhone 5, the iPad 4, iPod touch, iPod nano and iPad mini.he Lightning connector is very small. Where the Dock connector had 30 pins, the Lighting one has just eight signal pins-and that means it's much, much smaller, which helps Apple make super-slim devices such as the iPhone 5.
