Jinhangbiao Explanation-Type C interface charging data also hides many uses

Since the launch of the typec interface, more and more mobile phones have begun to adopt this interface, showing a trend of unified interfaces. Compared with the traditional microUSB socket, the typec interface has been greatly improved in speed and protocol type, of which reversible insertion is the iconic feature. But to unleash the true power of typec, not everyone can do it.

In order to solve the problem of inconsistent USB interface specifications, typec is a new interface developed by the USB standardization organization in 2014. For example, it can only transmit in one direction during charging. However, in order for the interface to achieve more functions, corresponding interface transmission protocol support is also needed. And on typec, the biggest impact on us is the USB transmission protocol of the interface. USB transmission protocols include usb2.0, usb3.1GEN1, usb3.1GEN2, usb4, etc. I hope that the faster the data transmission is, the higher the protocols supported by the typec interface will be!

Although many mobile phones today use typec interface, the old usb2.0 protocol is still used inside the interface, so why do they do this? In fact, this is also related to the cost of the interface! Today's mobile phone manufacturers do not hesitate to start price wars in order to seize the market. In order to reduce the price of mobile phones, the best way is to castrate the configuration of mobile phones. How to explain? In places you can't see, the typec interface is one of them. Due to real usb3.1.

The Typec interface can provide 10GB/s bandwidth, can transmit video streams through transfer, and can easily achieve bidirectional transmission power of more than 100W, but the cost is several times higher than USB2.0 and 3.0. Therefore, in order to save costs, mobile phone manufacturers just moved away from USB.

2.0 protocol, and then work hard on publicity. Some are even more exaggerated, directly telling you that typec is a thunderbolt interface, making you believe it.

As long as a mobile phone with a true thunderbolt interface typec is plugged into the typec expansion dock, you can connect a mouse and keyboard, write long text, or use office apps such as EXCLE and word. The mouse and keyboard can definitely greatly improve operating efficiency and facilitate mobile office work. Friends who like to play games can also experience computer-like game operations on their mobile phones.

In addition, a USB flash drive can be connected through the docking station, which is a lifesaver for those with insufficient mobile phone memory. Pictures, videos and other files that take up a lot of space can all be stored in the USB flash drive. After the USB flash drive is connected to the mobile phone, it can be opened and viewed directly without taking up space on the mobile phone.

If external USB devices can also implement traditional Android interfaces that support OTG functions, then the following two functions cannot be achieved by traditional Android micro interfaces.

Everyone has to know that typec supports audio transmission, because more and more mobile phones are canceling the 3.5mm headphone jack while using the typec interface. If you want to listen to music with wired headphones, you need a typec converter. The reason why you can use the typec interface to listen to music is because it supports audio output, which can theoretically improve the sound quality.
