Universal Serial Bus (English: Universal Serial Bus, abbreviation: USB) is a serial bus standard and a technical specification for input and output interfaces. It is widely used in information such as personal computers and mobile devices. Communication products, and expanded to photographic equipment, digital TV (set-top boxes), game consoles and other related fields.

usb interface type

1. B-5Pin

This interface can be said to be The most common interface. This interface is winning the attention of more and more manufacturers due to its excellent anti-misplug performance and relatively small size. Nowadays, this interface is widely used in card readers, MP3, and digital cameras. And on the mobile hard disk.

2. B-4Pin

This interface is commonly found in the following brands of digital products: Olympus’s C series and E series, and most of Kodak’s digital products Cameras, Samsung's MP3 products (such as Yepp), SONY's DSC series, Compaq's IPAQ series products.

Mini B type 4Pin also has another form, that is Mini B type 4Pin Flat. As the name suggests, this interface is flatter than the Mini B-type 4Pin and is widely used in devices.

3. B-8Pin

Compared with the previous ordinary type, this interface changes the original D-type connector into a circular connector, and for A bump is designed on one side to prevent misinsertion.

This kind of connector can be found in some Nikon digital cameras, and is more common in the CoolPix series. Although Nikon has always insisted on using this interface, some newer models, such as the D100 and CP2000, also use the most popular Mini B-type 5Pin interface.

4, B-8Pin-2×4

This interface is also a relatively common interface, such as iRiver’s famous MP3 series, which is known as “ Audio-Technica's 180TC and many other products in this series use this interface. The application range of this interface is quite wide, but after iRiver switched from the 3XX series to the Mini B-type 5Pin interface, this specification is obviously not as eye-catching as the Mini B-type 5Pin.

5. Micro USB

complies with the USB2.0 specification and supports a data transfer rate of 12Mbit/s. This module connects the control pins according to the Microport interface to facilitate connection with the host controller that supports the Microport interface.

The "Power Adapter and Charger Solution for Universal Mobile Terminals and Other ICT Equipment" was completed at the ITU-T Study Group 5 (SG5) Plenary Session held in Geneva, Switzerland on October 26, 2009. The framework standards were discussed and approved, and the application entered the approval process. This actually means that mobile phone charger standards will be unified around the world.

6, Type-C

Type-C is a brand new USB interface form, which was born with the latest USB 3.1 standard. Released by the USB-IF organization in August 2014, it is a brand-new interface developed by the USB standardization organization to solve the long-term disadvantages of USB interfaces such as inconsistent physical interface specifications and the only one-way transmission of power. It integrates charging, display, and data transmission. functions in one. The biggest feature of the Type-C interface is that it supports insertion in both front and back directions, officially solving the worldwide problem of "USB can never be plugged in correctly". It can be plugged in either way.

The TYPE-C hardware interface has obvious features, mainly including the following points:

(1) Supports symmetrical plugging and unplugging, solving the problem of reverse plugging in practical applications;

(2) The interface is slim and can support thinner and lighter devices, making the design of portable devices thinner and smaller;

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

(4) Support single port and dual port TYPE-C, flexible application.

(5) Supports two-way power transmission, both sending and receiving power.
