USB-C
USB-C (formerly known as USB Type-C ) is a 24-pin USB connector system that is characterized by its double, rotationally symmetrical connector. The USB Type-C specification 1.0 was published by the USB Implementers Forum and completed in August 2014. In July 2016 it was adopted by the IEC as "IEC 62680-1-3". A device with a Type-C connector does not necessarily implement USB, a USB power supply, or any alternative technology. For example, USB-C is now sold in most Android smartphones and many laptop manufacturers have a USB-C interface, which is usually adapted in parallel with Thunderbolt-3 .
Overview
target
The original goal of USB-C was the standardization and miniaturization of the now growing proliferation of physical connections to computers, tablets and smartphones. This contains:
- USB-A on the host,
- USB-B 2.0 standard, USB-B 2.0 mini, USB-B 2.0 micro, USB-B 3.0 standard, USB-B 3.0 mini, USB-B 3.0 micro on the devices,
- DVI, DisplayPort , Mini-DisplayPort, HDMI , Mini-HDMI and Micro-HDMI on the host,
- classic power supply, powered USB, USB-A with various current delivery capabilities and
- the 3.5 mm jack plug for connecting speakers, headphones and microphones.
You can practically use one semi-passive cable at the same time
- load a notebook
- connect one or two displays
- Listen to music.

Examples
Since the MacBook from 2015, Apple has relied entirely on USB-C and, at the same time, Thunderbolt-3 in its entire MacBook series. But at the market launch, acceptance for this innovation was limited. Many buyers were frustrated that they couldn't even connect a traditional wired mouse or SD card , and third-party vendors responded. They offered so-called hubs, with which the functionality with the old connections could be granted.
Practically all newer Android smartphones have a USB-C port.
