All Types of USB Pinout Diagrames

Universal Serial Bus connectors. These USB connectors let you attach mice, printers and other accessories to your computer quickly and easily. The operating system supports USB as well, so the installation of the device drivers is quick and easy, too. Compared to other ways of connecting devices to your computer (including parallel ports, serial ports and special cards that you install inside the computer’s case), USB devices are incredibly simple.

Inside a USB cable:

There are two wires for power — +5 volts (red) and ground (brown) — and a twisted pair (yellow and blue) of wires to carry the data. The cable is also shielded. The goal of USB is to end all of these headaches. The Universal Serial Bus gives you a single, standardized, easy-to-use way to connect up to 127 devices to a computer.
