2.USB Type-C interface, referred to as USB-C, is located at the bottom of smart phones and is mostly used for charging, data transmission and other purposes.
Note: the characteristics of USB Type-C interface are as follows:
A. Slim: Different from the traditional USB Type-A interface that is common in life, the new USB Type-C interface is greatly reduced in size, only 8.3*2.5mm, which is more suitable for use on increasingly miniaturized computing devices and can withstand 1000 repeated plugging and unplugging;
B, fast transmission speed: support USB3. 1 specification, and the data transmission speed can reach10 Gbps;
C, non-directionality: Similar to the Apple Lightning interface, the USB Type-C interface has no directionality requirement, that is, forward and backward insertion can complete pairing, which greatly improves the usability of the USB interface.
D, strong power supply capability: USB3. 1 Type-C interface can provide power output as high as 100W, and two-way power supply can be realized through USB Typc-C-C interface: it can not only charge the device itself, but also supply power to external devices, and the charging time of the device can be shortened by 2-4 times;
E. Strong expansibility: USB Type-C can transmit audio and video signals, and can be extended to a variety of audio and video output interfaces, such as HDMI, DVI, VGA interfaces, and even realize the extension of 4K resolution.
