A brief intro to USB

Universal Serial Bus (USB) was developed in the 1990s in an effort to simplify the connections between computers and peripheral devices. It has become widely popular due to its compatibility with many platforms and operating systems, its low cost of implementation, and its ease of use. Most computers that are built today come with several USB ports, and USB is the interface of choice for most home and office peripherals including printers, cameras, modems, and portable storage devices.


USB standards are developed and maintained by an industry body called the USB Implementers Forum (USB-IF). In its original specification, USB defined only two connector types: A and B. Revisions to the specification and demands on manufacturers have expanded the breadth of connectors used for USB devices, but the majority of USB products still use these A and B connector interfaces.


USB 3.0 A-Type

Known as "SuperSpeed", this A-style connector is commonly found on host controllers in computers and hubs, the A-style connector is a flat, rectangular interface. This interface holds the connection in place by friction which makes it very easy for users to connect and disconnect. Instead of round pins, the connector uses flat contacts which can withstand continuous attachment and removal very well. The A-socket connector provides a "downstream" connection that is intended for use solely on host controllers and hubs. This connector is similar in size and shape to the A-Type connector used in USB 2.0 & USB 1.1 applications. However, the USB 3.0 A-type has additional pins that are not found in the USB 2.0 & USB 1.1 A-Type. The USB 3.0 connector is designed for USB SuperSpeed applications; however, it will carry data from slower speed connections, and it is backwards compatible with USB 2.0 ports. USB 3.0 A connectors are often blue in color to help identify them from previous versions.



USB C-Type


The USB-C or USB Type-C connector is the newest USB connector on the market. The USB-C connector has a reversible/symmetrical design and can be plugged into any USB-C device using either end.

A USB-C cable is capable of carrying USB 3.1, USB 3.0, USB 2.0, and USB 1.1 signals.

The USB-C is commonly paired with the USB-A, USB-B, USB Micro-B, and other USB connectors when

supporting previous versions of the USB specification. USB-C can be adapted to work with each of these

legacy connectors.

When connecting two USB 3.1 devices, the USB-C cable will support data transfer rates that are twice the

speed of existing USB technology (up to 10Gbit/s), enhanced power delivery of up to 20 volts, 5 amps, and

100 watts for power and charging, and built-in support for DisplayPort video and four channel audio

(speaker and microphone).
