This article introduces you what usb interface, the content is very detailed, interested friends can use for reference, hope to be helpful to you.

Type of usb interface

1 、 B-5Pin

This kind of interface can be said to be the most common interface. Because of its excellent anti-misinsertion performance and relatively small size, this kind of interface is attracting the attention of more and more manufacturers. Nowadays, this interface is widely used in card readers, MP3, digital cameras and mobile hard drives.

2 、 B-4Pin

This interface is common in the following brands of digital products: Olympus C series and E series, most Kodak digital cameras, Samsung MP3 products (such as Yepp), SONY DSC series, Compaq IPAQ products.

There is another form of Mini B 4Pin, which is Mini B 4Pin Flat. As the name implies, this interface is more flat than Mini B 4Pin and is widely used in devices.

3 、 B-8Pin

Compared with the previous ordinary type, this kind of interface changes the original D-type joint to a circular joint, and a bulge is designed to prevent it from being mistakenly inserted to one side.

This kind of connector can be found in some Nikon digital cameras, especially in the CoolPix series. Although Nikon has always used this interface, it has also adopted the most popular Mini B 5Pin interface in some newer models, such as D100 and CP2000.

4. B-8Pin-2 × 4

This kind of interface is also a relatively common interface, such as iRiver's famous MP3 series, in which the so-called "iron triangle" 180TC, and many other products in this series use this interface. This kind of interface has a wide range of applications, but after the iRiver has been completely changed from 3XX series to Mini B 5Pin interface, this specification is obviously not as eye-catching as Mini B 5Pin.

5 、 Micro USB

It conforms to the USB2.0 specification and supports the data transfer rate of 12Mbit/s. The module controls the pins according to the Microport interface so that it is easy to connect with the main controller that supports the Microport interface.

The framework standard of "Power Adapter and Charger Scheme for General Mobile Terminal and other ICT equipment" was discussed and adopted at the Plenary meeting of ITU-T Fifth Research Group (SG5) held in Geneva, Switzerland on October 26th, and applied to enter the approval process. This actually means that mobile phone charger standards will be unified all over the world.

6 、 Type-C

Type-C, a new form of USB interface, came out with the latest USB 3.1standard. Released by USB-IF in August 2014, it is a new interface developed by USB Standardization Organization to solve the disadvantages of USB interface such as non-uniform physical interface specification and one-way transmission of electric energy. It integrates charging, display, data transmission and other functions. The biggest feature of Type-C interface is that it supports insertion in both positive and negative directions, which formally solves the worldwide problem that "USB will never be plugged in".

The characteristics of TYPE-C hardware interface are obvious, which mainly include the following points:

(1) support positive and anti-symmetrical plugging to solve the problem that anti-plugging can not be inserted in practical applications.

(2) the interface is thin and can support lighter and thinner devices, which can make the design of portable devices thinner and smaller.

(3) support higher power transmission, up to 100 watts, and support more high-power load devices.

(4) single-port and dual-port TYPE-C are supported, and the application is flexible.

(5) two-way power transmission is supported, both power transmission and power receiving are possible.

About which usb interfaces are shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
