USB-C Complete Guide

Now USB-C is the most popular high-speed and charging interface.

USB-A

The most common and familiar USB connector shape is USB Type-A, which is currently used on the majority of computer equipment and peripherals (although that is quickly changing). It is also used on many other devices, including those that utilize its Mini-A and Micro-A variants (see feature image above). Gaining popularity in the mid 90’s, standard USB Type-A connectors are rectangular and have a distinct top and bottom. This requires them to be oriented properly in order to be plugged in.

USB-B

The more square shaped USB Type-B is somewhat less common but is electrically identical to USB Type-A connectors. USB Type-B connectors are frequently used on printers, though they can also be found on some monitors and USB hubs. The Mini-B and Micro-B connectors, like their Type-A counterparts, are found on a wide range of electronics, from tablets and handheld GPS devices to cell phones.

Micro-USB

A micro USB is a miniaturized version of the Universal Serial Bus interface developed for connecting compact and mobile devices, such as smartphones, MP3 players, Global Positioning System devices, printers and digital cameras.

Micro USB connectors exist in four connector types: micro USB type A, micro USB type B, micro USB 2.0, and micro USB 3.0. Micro USB 3.0 is much like micro type B but with an additional pin group on the side for twice the wires, enabling USB 3.0’s greater speed.

USB-C

USB-C refers to the physical shape of the newest USB connector. (The USB Type-C connector shouldn’t be confused with the USB 3.1 or USB 3.2 standards.).

The USB Type-C connector is smaller than both Type-A and Type-B, oval-shaped, symmetrical, and reversible, meaning there is no “wrong way” to plug it in. This eliminates one of the most common complaints about USB Type-A. This newest USB connector is intended to replace the other existing USB form factors and provide a future-proof, fully-featured option for hardware designers to standardize on.

USB Type-C ports are becoming more and more common on mobile devices and consumer hardware. On the other hand, the industrial PC (IPC) market is just beginning to integrate USB Type-C ports into the latest generation of commercial devices.

Finally, we should note that while USB Type-A and USB Type-B have traditionally been written using the word “type” as shown, USB Type-C is increasingly being written as simply USB-C.
