The first compatible devices were the iPhone 5, the iPod Touch (5th generation), and the iPod Nano (7th generation). It would soon be integrated with all new hardware and devices that was to be announced at the same event. The Lightning connector was introduced on September 12, 2012 ( ), as an upgrade to the 30-pin dock connector. The male connector is indented on each side to match up with corresponding points inside the female port to provide a retention advantage. The male Lightning connector is symmetrical (same pins on either side), so it can be inserted into a female Lightning port in either orientation. Using 8 pins instead of 30, Lightning is more dense than its predecessor, which was integrated with devices like the iPhone 4 and the iPad 2. Introduced on September 12, 2012 ( ), to replace its predecessor, the 30-pin dock connector, the Lightning connector is used to connect Apple mobile devices like iPhones, iPads, and iPods to host computers, external monitors, cameras, USB battery chargers, and other peripherals.
Lightning is a proprietary computer bus and power connector created and designed by Apple Inc. Lane 0 and 1 may swap in IC of device connector (lanes don't swap if the accessory identification chip is connected to the ID0 pin)
