The origin of the Lightning interface
Apple high-speed multifunction I/O interface is September 12, 2012, the United States, San Francisco, the Grass Conference center Apple released a new lightning Dock interface, Chinese can be translated into the "lightning" interface. The release of the new interface standard also means that Apple uses the 30-pin dock interface for up to 9 years to be formally replaced.
After the Lightning interface was released, many fans complained about it. However, if you understand the Lightning interface's antecedents and consequences and technical advantages, you may not think so.
In today's increasingly thin Apple equipment, space saving is very important. Apple has a very loud name for the new interface------Lightning, the new interface has 8Pin contacts on both sides, and regardless of the positive and negative, no matter how you insert can work correctly. So you don't have to worry about the problem. Apple is also officially claiming that the new interface is not only easier to use, but also more durable. At the same time, it is pointed out that the new lightning interface is a "full digit" and has "adaptive function" interface. "Adaptive" means that it is able to use different accessories to pass through the interface for the specific signal required by the accessories. Like the previous 30Pin dock interface, the new lightning interface also supports video output.
Of course, the new lightning interface also has a very big advantage is the size. It is 80% smaller than the original 30Pin interface, which means that your device needs to have at least 80% less space reserved for this interface. And this does not count from 30Pin to 8Pin of related circuit complexity reduction.
