What is a USB Type C cable ?
USB-C, also known as USB Type-C, is a 24-pin USB connector system, which is distinguished by its two-fold rotationally-symmetrical connector
In reality, USB-C devices do not necessarily support USB 3.1 or USB Power Delivery. The current theoretical value can reach USB3.1 standard only USB-C to USC-C, or USB-C male to female, and the length should not exceed 1M, USB-C cable that can be seen on the market, mainly TYPE A to USB-C, but TYPE A currently has a maximum of 9 PIN, its data transmission can only reach USB3.0 standard. The simpler USB2. 0 TYPE A has only 5 PIN, and its data transmission can only reach the USB2.0 standard, but their charging ability will be greatly enhanced after adding the PCB to the USB-C connector.
The 24-pin double-sided connector is slightly larger than the micro-B connector, with a USB-C port measuring 8.4 millimetres (0.33 in) by 2.6 millimetres (0.10 in). Two kind (gender) of connectors exist, female (receptacle) and male (plug).
An increasing number of motherboards, notebooks, tablet computers, smartphones, hard disk drives, USB hubs and other devices released from 2014 onwards feature USB-C receptacles.
Currently, DisplayPort is the most widely implemented alternate mode, and is used to provide video output on devices that do not have standard-size DisplayPort or HDMI ports, such as smartphones and laptops. A USB-C multiport adapter converts the device's native video stream to DisplayPort/HDMI/VGA, allowing it to be displayed on an external display, such as a television set or computer monitor.
The receptacle features four power and four ground pins, two differential pairs for high-speed USB data (though they are connected together on devices), four shielded differential pairs for Enhanced SuperSpeed data (two transmit and two receive pairs), two Sideband Use (SBU) pins, and two Configuration Channel (CC) pins
