Information

According to the characteristics of the supported devices, it is divided into USB Type A/B/C/Mini/Micro.

1. MiniUSB A/B: larger than the micro USB interface, also known as mini USB.

Generally used in mobile devices such as digital cameras, digital video cameras, measuring instruments and mobile hard disks.

2. Micro USB A/B interface: flat trapezoid

The Micro-USB specification supports the USB OTG function, which provides data transmission and charging functions. It is a portable version of the USB 2.0 specification, smaller than the Mini USB interface.

Micro USB is now mainly divided into A type, B type, and USB3.0 B type.

Among them, Micro USB A is the most widely used, and is called "Android port" or "Android cable" by many people, because Android phones use this interface.

Compared with Mini USB, it is smaller and thinner. Many mobile devices, including tablet computers, mobile hard drives, digital cameras, and cameras, have screened the Mini USB port and switched to Micro USB A.

3. USB Type A, USB Type B, Type C

USB Type A: This rectangular USB interface is commonly used on our computers. USB2.0 is a black interface, and USB3.0 is a blue interface.

USB Type B: Generally used for 3.5-inch mobile hard drives, printers, monitors, etc.

USB type-C interface: oval, used for smartphones, can be plugged on both sides. It is a new standard interface that has become popular in recent years.

The USB Type C interface was presented after USB 3.1. The highlights of this interface are thinner design, faster transmission speed (up to 10Gbps) and more powerful power transmission (up to 100W).

The biggest feature of the Type-C double-sided pluggable interface is that it supports double-sided insertion of the USB interface, which is mainly aimed at more frivolous and slender devices (in the future, the interface of mobile phones and tablets may be unified, replacing the Micro USB interface).

The biggest feature of the Type-C double-sided pluggable interface is that it supports the double-sided insertion of the USB interface, which officially solves the worldwide problem of "USB can never be inserted correctly", and the front and back can be inserted casually.
