Lightning is a proprietary I / O interface designed by Apple for its mobile devices, such as the iPhone , iPad, and iPod. It was first introduced in September 2012, along with the then iPhone 5 and new iPod models.
At the same time, they were added to iPads, for which first generation 4th generation iPad and first generation iPad mini were used. This Lightning interface replaced the earlier “dock connector,” which was previously used in 2003 with Apple products.
This Lightning connector has eight pins and is about a third the size of a 30-pin dock connector. In place of mobile latches on the side, these Lightning connector has small divots on each side which allow it to snap in different places.
Without any magnets or clips, these Lightning connection is designed to be powerful enough to hold the device upside down, without any cable detaching.
In place of other I / O interfaces, such as USB , Firewire, and earlier dock connectors, these Lightning connectors are actually reversible. In this the connection is completely symmetrical and the connector can be inserted in a lightning port in any way. This means that it is impossible to insert the cable upside down, which makes it easy to plug in and also helps reduce wear and tear in the interface.
In this, the order of pins is recognized dynamically by the device when the connection is made, which allows power and data to flow through correct channels.
The name ” Lightning ” is often correlated with Thunderbolt, another I / O port that Apple created at the same time as the Lightning interface was introduced.
But unlike Thunderbolt, Lightning is completely proprietary and is used only with Apple products. By the way, most mobile devices (like Android phones) have standard mini-USB or micro-USB ports, so if you have an Apple device, you will need a lightning cable to charge and data transfer. to do.
