One minute for popular science: What is USB Type-C sacred?


What is USB Type-C sacred? It is a combination of "fast, strong, and small" as one of the three major advantages, but also regardless of the pros and cons, even as an epoch-making product for the USB interface, to solve the "USB is always not plugged in" the world's problems.

Apple 12-inch MacBook body Type-C interface details


Since Apple released the new MacBook, there are a lot of people talking about USB Type-C, saying that it has the advantages of small size, positive and negative can be inserted, speed (10Gbps), saying that it represents the development direction of the USB interface, And admired Apple's ability to innovate.

       To tell the truth, Apple does have "mastery of core technology," but it has to be innovative, especially with black technology like USB Type-C. Sony, Motorola, and Nokia have to fling Apple for a few streets, but Apple has "inherited innovation." The peculiar function, that is to say something is invented by others, but Apple can always make it shine.

     For example, this Type-C interface, the Type-C standard is neither designated by Apple nor introduced by Apple. The Type-C interface provided by the Nokia N1 Tablet appears two months earlier than the new Macbook (silently Nokia Flowing tears). Of course, this is a digression.

  1. What exactly is USB Type-C?


USB Type-C (abbreviated as USB-C), it has a brand new interface size and a slightly cool name. It is very easy to make this partner who first heard the term think that this is a brand-new USB standard, but actually Not on it. Type-C is only part of the USB 3.1 standard, not a new standard.

        Type-C was born soon and at the end of 2013, the Type-C connector renderings came out. In 2014, the USB 3.1 standard was already done. It is a specification of a new type of USB cable and connector and is a complete set of new USB physical specifications.


It is as thin and light as the Lightning interface in the iPhone, and can be expanded into three interfaces: power/USB transfer/VGA or HDMI. Through the adapter, it can also be compatible with previous generation interfaces such as USB3.0 and USB2.0.

       It should be noted that, similar to the common USB 2.0, the USB 3.1 standard still has Type-A (common in computer hosts) and Type-B (common in Android phones) and other interfaces, so Type-C is only USB 3.1 high-speed data transmission One, not the only one.

2, USB3.1 interface and Type-C


USB interface is very confusing, big say there is 2.0, 3.0, and now USB3.1, smaller said more branches. In the industry, the USB 2.0 interface is black and the USB 3.0 interface is made blue.

As for the color of USB3.1, there is no consensus yet, but Asustek has introduced a motherboard with a Type-A USB3.1 interface, and its interface color is blue-green. Although the USB Society does not specify the colors of USB3.1, it will be inevitable to distinguish them by color.


So, does USB3.1 have a relationship with Type-C? The Type-C specification is based on the USB3.1 standard, so USB3.1 can be made into Type-C, Type-A and other types, but Type-C is not equal to USB3.1.

For example, the Nokia N1 tablet uses the USB 2.0 specification Type-C interface, while the Asus Z97-K/USB 3.1 uses the standard Type-A USB 3.1 interface.

3, we commonly used three kinds of USB interface

(1) Type-A: Standard Edition USB Interface

Type-A is our most common type of USB interface, commonly used on computers. But it has some significant problems: There are direction requirements. The connector (male) must be inserted into the connector (mother) in a certain direction, but the insertion process is often faulty because of the close proximity of the two sides of the USB male connector.

(2) Micro-B: USB standard for mobile devices

Most of the current Android phones use the Micro USB interface (USB Micro-B), which is still widely used in various mobile portable devices.

(3) USB Type-C: or will become mainstream

Although Type-C appears shortly, it is foreseeable that with the maturity of USB Type-C technology, various types of notebooks, tablet computers, and even smart phones in the future will begin to popularize the USB Type-C interface.
