Talking about the Development of USB

Since the advent of the PC, the development of the interface has continued to evolve, and some have disappeared over time. Among them, USB is undoubtedly one of the most enduring interfaces. From the appearance of USB 1.0 in 1996, it has been nearly 20 years. History, and the interface speed has also evolved from USB1.0 to USB3.1. Each version of the innovation has brought higher transmission speeds. USB transmission speed has developed from 1.0 (1.5Mbps), 2.0 (480Mbps), 3.0 (5Gbps) to the maximum transmission speed of 10Gbps today. At the same time of speed innovation, each generation of USB interface types has also evolved and developed. Today USB Interface 3.1 Manufacturer will talk about the development of USB interface types.

At present, the very popular USB3.1 TYPE-C interface appears, and its popularity is due to the world's attention to the new Apple conference, the latest release of the MacBook port has been changed, the entire machine does not have any remaining interfaces, only with A USB3.1 Type-C interface is precisely because of this. This interface has attracted people's attention, but many consumers do not know it well, and even mistakenly believe that the USB3.1 Type-C interface is an invention of Apple. What's more, I think it is the same product as Apple's Lightning cable, because they are similar in length, and the same feature is that they can be inserted at will regardless of positive and negative.

In order to let everyone understand this interface more clearly, let us first review the USB interfaces we have seen over the years. This is our most common. Before the USB2.0 era, USB ports were divided into many types:

Before USB2.0 era (speed up to 480Mbps). In fact, it is easier to remember a few interfaces:

Type A: Generally used for PC;

Type B: Generally used for 3.5-inch mobile hard drives, as well as printers, monitors and other connections;

Mini-USB: Generally used in digital cameras, digital video cameras, measuring instruments and mobile hard drives.

A portable version of the USB 2.0 standard-the Micro USB port appears. In the USB2.0 era, the Micro USB port appeared. This is a portable version of the USB 2.0 standard. The next-generation specification of Mini USB is smaller than the Mini USB interface used in some early mobile phones.

Micro USB interface: I believe everyone is very familiar with this interface, because most Android phones currently use this interface.

USB3.0 Era-New Micro USB 3.0 Type B interface appears (speed up to 5Gbps). In the era of USB 3.0, a new type of Micro USB 3.0 B-type interface has appeared. Micro USB 3.0 B-type interface: used for USB 3.0 devices such as USB 3.0 mobile hard drives.

USB Type C 3.1 Interface

The latest USB Type C 3.1 Interface is now available (up to 10Gbps). USB 3.1 was born in 2013. The organization responsible for the formulation of the USB standard is the USB Promoter Group. This organization is also the designer of the USB Type-C interface. USB 3.1 has three connection interfaces, which are Type-A (Standard-A). , Type-B (Micro-B), and Type-C.

Type-A is also the most widely used USB A type interface for computer connection; Type-B is the above Micro B type interface, which is mainly used in smartphones and tablets; and Type-C is mainly for thinner and lighter More slim devices (in the future, the interface of mobile phones and tablets may be unified to replace the Micro USB interface).

Every upgrade of USB faces the same problem, that is, the recognition and cooperation of major component manufacturers. In the USB3.0 era, the motherboard interfaces produced by major motherboard manufacturers are still mostly USB2.0 interfaces. Nowadays, to achieve The development of USB Interface 3.1 also requires the full support of hardware such as motherboards. With this upgrade, mobile phones and tablets may be able to promote the development of USB 3.1 faster.
