USB TYPE-C interface
USB-C is a new USB connection standard, and its name is designed to help users distinguish it from the previous USB-A and USB-B standards.
At present, the most familiar USB form is Type-A. In the decades of computer development, USB Type-A has not improved any design or connection standards compared to when it was originally born.
However, with the development of the 4.0 technology era, the device is becoming thinner and thinner, and USB-A connectors are no longer suitable. With the success of the Lightning interface for Apple devices only, the USB type interface has also reached a time when it has to make changes.
The most commonly used USB connector USB-A
USB-C standard was first unveiled in 2014. However, it was not until 2019 that USB-C was used on devices and became well-known.
Now, USB-C not only replaces traditional USB, Thunder bolt and Display Port connections, but on some mobile devices we can also see USB-C type interfaces used to replace the 3.5mm audio port.
Not only that, it also integrates USB Power Deliverv technology to improve power transmission over USB connection.

Most USB-C ports are based on the USB3.1 data transmission standard. USB3.1's second-generation protocol can theoretically provide data speeds up to 10Gbps.
USB-A, USB-B, micro USB and mini USB all share the same basic internal connection (just the port shape is different), and the faster 3.0 cables and ports add additional high-speed data channels. The number of pins in USB-C has tripled compared to USB3.0, reaching 24.
Various USB interfaces
USB Type-C interface is a type of USB interface. There are currently four main interface types for USB interface:
1 and USB Type-A. This interface type is our most common USB interface and is mainly used on computers, chargers, mice, keyboards, USB disks and other devices.
2, USB Type-B, this type of interface is mainly used on printers and other devices, and there is no common type-A interface.
3, Micro-B, we have seen this kind of interface, which is the interface of mobile phone charger.
4, USB Type-C, this is our protagonist today, and it is the future development trend of USB interfaces. The transmission rate of
USB2.0 is 480Mbps, USB3.0 is 5.0Gbps, and USB3.1 is 10.0Gbps.
Its transmission rate is divided into: USB2.0 USB3.0 USB3.1. Features of
USB-C:
1, ultra-thin
USB-C is a very small interface. The old-fashioned USB port of is 14mm * 6.5mm, while USB-C is only 8.4mm * 2.6mm. Compared with traditional USB, is only 1/3 of its size. This is also its advantage when integrated on thin and light devices, which is a new design trend for all technical equipment in the 21st century.
3, fast transmission speed
USB-Ch supports USB 3.1 standard. According to , the maximum transmission rate of USB-C port is 10Gb per second, which is much faster than USB3.0 (double the current USB3.0 standard capability).
2.
USB Type-C is elliptical in shape. The front and back sides of this interface are exactly the same, and both sides can be inserted and charged. The same as the Lightning interface, will not have any problems regardless of forward insertion and reverse inspection. It is said to be able to withstand 10,000 repeated plug-ins and unplugs.
2, high transmission power
supports high current and high voltage charging, which helps improve charging speed; This interface can support up to 20V voltage and 5A current through 3A current , and can support up to 100W of transmission power, which greatly increases the charging speed of the mobile phone, so it can be used to charge on large portable devices such as laptops and tablets. So it is no exaggeration to say that usb-c will gradually replace all current USB connection methods.
4, bidirectional transmission
is not like the old USB port, and the power can only be transmitted in one direction. The power transmission of the USB-C port is bidirectional, which means it can have two ways of sending power. uses the USB Typc-C interface to charge the device itself and power external devices.
4, has video transmission function, supports external device
In addition to power and data transmission, the prominent point of USB-C compared with the previous B and A types is that it supports image transmission to the screen. can transmit audio and video signals, so it can be expanded to a variety of audio and video output interfaces, such as headphones with commonly used TYPC-C interfaces. It can replace the mainstream video transmission ports today, such as HDMI, VGA, and Display Port.
5. High popularity:
Now major terminal manufacturers have integrated USB-c ports into their products, and the usage rate of new mobile phone terminals is as high as more than 90%. In addition, similar to micro USB interface, USB-C can be produced by any technology company without requiring too professional technology, so the popularity of this USB-C standard will become increasingly higher.
USB-C has been widely used in various mobile devices and personal computers, becoming the data interface with the broadest development prospects.
