What are the advantages of USB Type-c interface?

mentioned USB Type-c Interface (hereinafter referred to as USB-C), the first can think of is the USB-C interface can be positive and negative, very comfortable to use. Learn more may also support USB-C interface faster, up to 5Gbps or 10Gbps, others may know that USB-C has 100W power supply capability, readers of our news will also know that Intel's Thunderbolt 3 interface is also USB-C interface, It not only speeds up to 40Gbps, but also transmits video to support dual 4K output. As a result, the USB-C interface is virtually counter-existent with wood, all kinds of omnipotence, really beyond all interfaces.

Those myths about USB-C: Actually it's just a physical structure specification, with speed, power supply okay

In fact, the various advantages of the USB-C interface mentioned above have many misunderstandings, some of the right, the USB-C interface can do this, but the USB-C interface itself just defines a new physical structure, whether USB 3.0 or USB 3.1 or the current USB 2.0, they can all do the USB-C interface.

As for the 100W power supply, that is the credit of the USB power delivery specification, and 100W output requires that the 20v/5a,usb-c voltage is still 5V, and now does not achieve 100W output.

There are video output, those features are more advanced value-added, not only to see the USB-C interface, but also to see the DP, HDMI and other specifications and vendor support.

USB-C: A mouthful of heavy mouth, all the mouth to be one

Why do you want to do USB-C interface? We can look at what's going on with the USB interface now.--USB is a Universal serial bus interface, the word general does do, the current we use the peripheral is the most convenient USB devices, but with the replacement of USB interface, in order to meet different market applications, USB interface also derived from the Type-a , Type-b interface, these two interfaces also have the standard type, Mirco (many of the hard disk base is Micro-b interface) and mini (smartphone, tablet with the most) such sub-classification, more pit Daddy is USB 2.0 and USB 3.0 Mini, Mirco interface is not universal. Now is the USB 3.1 era, if you continue this situation, it is estimated to make a new interface, this can be ashamed of the name of the universal interface.

USB interface is a universal interface, but the derivative version is more and more, it is inconvenient

In this case, the official USB organization Usb-if feel like, and then toss it all messed up, they do not forget beginner's mind (big mistake), so they created a USB-C interface, the interface is defined as a new generation of the interface specifications, and to adapt to smartphones, tablets, notebooks and other mobile devices.

The USB-C interface is future-oriented and adapts to a variety of interface protocols, so it has a total of 24 pins, while the 3.0 interface is typically 9 to 11, and USB 2 has only 4 pins. But don't worry, the increase in the number of pins does not cause the USB-C interface to become larger, in fact it also reduces the volume (relative to the standard port), to meet the needs of mobile devices.

We can use the USB-C interface as a "basket", the usb-if redefined this basket is very ingenious, the Aunt (USB 2.0) can take it to the market to buy vegetables when the basket, girls (USB 3.1) can also take it shopping at that time Shang pin use, and it also has a variety of advantages to dig.

Of course, although the usbc-c are all good, but also not without shortcomings-if these are the shortcomings of the words mentioned below. The first is USB-C is not compatible with other A, B interfaces, second it looks small, but the length of the USB-C interface is 8.6X2.4MM,USB 2.0 The Mini-b interface is the 6.8x3.0mm,mirco-b interface is 6.85x1.80mm, so it's actually a little bigger.

This "disadvantage" compared to the advantages of the USB-C interface is negligible, we should pay attention to the advantages of the USB-C interface.

One of the advantages of USB-C interface: Reversible

User USB Interface Player 100% have encountered the "front plug wrong, the reverse plug is not right, the front plug on the right", I think that only a bit of USB-C is enough to replace the other interface, because USB-C is the front and back can plug, said the professional point is the interface has no directionality.

I'm sure you've had this problem with the USB interface.

This is also a factor in the place where the fruit powder is proud of the Android user, because Apple's iphone has been designed so early that the iphone 5 Lightning interface can be plugged in without the need to recognize the pros and cons of the Android phone (and, worse, the different manufacturers ' mini USB interface design is also different, it is worth to spit groove millet is their mobile phone also do the USB interface to look as wide, more difficult to distinguish, and more comfortable to use.

USB-C Interface Benefits two: stronger power supply

Although the 100W USB power supply is not the same as the C-USB interface, but the power of the USB-C interface is actually enhanced, we know that the supply current of the 2.0 is 0.5A,USB 3.0 to 0.9a,usb 3.1. But the current of the USB-C interface has not only 1.5A and 3 a optional (standard cable), the interface can carry the current is actually 5 A, so the theory of its power supply capacity of up to 25W, which is already more than a lot of QC 2.0 fast charge is higher.

Of course, in fact, manufacturers can do a lot of power supply capacity is not necessarily the case, if you can achieve the PD 2.0 specification, then the USB-C 100% specification can also really do 100W power output, this time do not charge, with the general notebook are no problem, Apple's NMB laptop is done with a USB-C interface.

In addition, the USB-C interface also supports bidirectional power supply, it can accept the charger power supply, but also as a charger external output current, Google's pro-son Nexus 5x/6p mobile phone has this function. But two-way charging this feature is USB-C can do, but not that only USB-C can do, before Huawei's Mate 7, such as the use of USB-C interface phone can do this function, can be external charging.

USB-C Interface benefits three: faster

We still have to go back to the speed of transmission, although the USB-C interface is the minimum requirement is 2.0 speed, but such a good interface only with USB 2.0 is obviously wasteful, it can do USB 3.0 or even USB 3.1 speed standard, this depends on the manufacturer's choice.

Apple on the NMB notebook with the USB 3.01 GEN1 standard speed, in fact, is the 5Gbps USB 3.0 speed. In the mobile phone, Lenovo Magic Factory's Zuk Z1 is the first USB 3.0 speed-C interface phone, other manufacturers including Google's Nexus 5x/6p are still USB 2.0 speed.

In other words, the flash memory used by smartphones, although the internal speed is relatively high, but the speed of connecting the computer is not very good, most of the phone even better USB flash drive is not running, so the demand for USB 3.0 is not high, and USB 3.0 on the phone signal interference, Samsung in note 3 on the use of USB 3.0, the result is not turned on by default, and later the phone directly cancels the USB 3.0 support.

USB-C Interface Benefits Four: capable of transmitting video

USB-C Interface A birth is all the love in one, not only in their own brothers the most attention, other industries also fancy the development potential of USB-C interface, have to USB-C matchmaking to expand its functionality. Video electronic Standards organization VESA on the joint usb-if launched the "DisplayPort over USB-C" program, which lets the USB-C interface with the DP video transmission function, later developed, it is estimated to be able to replace the DP interface and DP line.

USB-C interface can also be used as DP video output

In this regard, the faster is the Intel Lightning 3 (Thunderbolt 3), this June, when Intel released the Lightning 3 standard, in addition to the speed of 40Gbps, another obvious change is to use the USB-C interface instead of the previous mini DP interface, Can even support dual 4K output, high performance do not want to.

The USB-C interface of Apple's NMB notebook now also has the DP output capability, which supports the native DP 1.2 output, and the VGA and HDMI output can also be achieved via the adapter.

With the expansion of other specifications, the USB-C interface may have more features, and the above four points will be strong enough. More and more motherboards supporting USB-C interface in 2015, laptops breaking ice on Apple NMB, and USB-C interfaces in smartphones and tablets are starting to emerge, so let's see which phones and tablets are using this interface.

USB-C Interface mobile phone, tablet inventory currently listed

Tablet for USB-C interface:

If not mistaken, the Nokia brand, Foxconn's N1 tablet is the first tablet to use the USB-C interface, but the tablet is too weak to exist on the market. Dell's Venue 8, venue Pro tablet and HP's Pavilion X2 10 tablet have also been used on the USB-C interface in the second half of the year.

In general, the USB-C interface is the trend, not only for smartphones, including PCs, notebooks, tablets and IoT devices are likely to fully upgrade to the USB-C interface, but that is later, on the current look at the USB-C interface of the mobile phone in addition to play a positive and negative plug, in the charging, The high-speed transmission and so on do not have any action, no matter how good they blow, now upgrade USB-C interface can only be symbolic meaning more than the actual meaning, and because the data line is not universal, and sometimes more trouble than convenient, this problem can be a trouble before the USB-C interface mass popularization.
