Hello, everyone, MY name is Data-mining, alias Liuzhen007 (Chinese Bond, a code-tapping Bond). I have worked for traditional radio and television giants and audio and video Internet companies successively. I have rich experience in audio and video live broadcast and on-demand. Very deep understanding of WebRTC, FFmpeg and Electron.

The body of the

In daily life, we have used a variety of data lines, and the difference between these data lines is mainly in the interface, including Micro USB port, Type C port, Lightning port, Pin30 port and so on. For a very simple example, if you want to charge your phone, you have to choose the right cable. Today we will briefly introduce and distinguish the common data line interface in life.

1. The Micro USB interface

This port is a portable version of the USB 2.0 standard. To prevent blind insertion, it can only be inserted on one side, supports THE OTG function, and is compatible with USB1.1 and USB 2.0. Belongs to the relatively old interface standard, some old devices are still widely used in this interface, at present, the scope of use is relatively wide.

2.USB Type C port

The interface is a USB 3.1 standard connection interface, with positive and negative plug, fast transmission speed and so on. This interface is based on the USB 3.1 standard, but not all devices using this interface support USB 3.1 standard.

(3) from the interface

This is a high-speed, multifunctional I/O interface designed by Apple that has been included in all new iphones and ipads since the iPhone 5. There are 8 contacts on both sides of the Lightning interface, which can be inserted into both sides of the Lightning interface, and can transfer specific signals required by different accessories.

4.30 the Pin interface

Apple’s proprietary port, which has been in use for nine years, is used in the famous iPhone 4 and 4S. Apple’s 30-pin port is relatively large, but it offers charging, high-speed data transmission, audio output, and a console.

There’s also the nearly obsolete Nokia round port and the Mini USB port commonly used in Chinese shanzhai phones.
