Interface science
What are Lightning port and USB-C port, and what are the differences? Why a small charging interface will be valued by the European Parliament, the following charging head network in detail.
In 2012, Apple used the new Lightning interface on iPhone 5, which was the first consumer electronic product interface that supported both positive and negative plug, and its advanced nature was "a clean SLATE". It was not until nearly two years after the launch of iPhone 5 that the first draft of today's more mainstream Type-C interface was completed.
The Lightning interface has two independent differential channels controlled by the chip, and the contacts on both sides are connected through internal channels.
The appearance is the eight contacts on the Lightning interface as we can see, and the white part of the wrapping pin is to make these pins insulated from each other and have the function of grounding.
The name definition of 8 pins on both sides of Lightning interface is shown in the data:
PWR: power supply; GND: ground cable.
ID0/ID1: used to identify the positive side or accessory type ID identification signal pin;
L0p, L0n, L1n, L1p: signal pins used for data transmission.
The mother seat of Lightning data cable interface is a common iPhone interface, with 8 contacts on a single internal side. Such internal structure determines that the normal identification and work of the data cable can be ensured regardless of the connection mode of the front and back of the pin. In recent years, Apple has strictly cracked down on third-party accessories. The identification chip is added into the device. When using third-party accessories, iPhone will prompt uncertified accessories and disconnect the connection or do not support querying the battery health after replacing the battery.
