A Look at Micro USB Connectors and their Uses


Developed in 1994, the Universal Serial Bus, abbreviated USB signifies the connection protocols for communications between electronic devices via cables and other connectors. The electronic devices can be anything among mobile phones, cameras, keyboards, printers, media players and so on. The micro USB is a miniature version of this serial bus that does a similar work of establishing a connection between peripheral devices and computers.

The USB has a rich history. Seven companies brainstormed to come up with a solution that will enhance the usability factor of the existing interfaces at that time. These companies are IBM, Microsoft, Compaq, Intel, DEC, Nortel and NEC. They addressed the rising problems of the complications in software configurations of devices to come up with a simpler and easy-to-use version that would solve all problems. And this is how the micro USBs came into being.

They have trumped the usability card and have made their ways into everyone’s digital accessory list. They have made connections simpler while taking the usability factor to newer heights.

Both of the above types can be further classified into a few more categories that differ from each other in height, PCB position and presence of plastic locating pegs and through-hole shell stakes.

Mobile phones nowadays use the Micro USB A-Type commonly. It is a compact design than generally comes with 5 pins.

The Micro USB B Type is also a usually found in mobile phones nowadays. The number of contacts is 5 and it comes with a black-coloured receptacle. The PCB position could either be in the bottom or in the middle. It has a horizontal orientation and requires a B type mating cable.

The Micro USB AB Type works with either a USB A or a USB B connection. This also comes with a 5 pin design with the PCB type being a surface mount one. The orientation is horizontal and the mating cable type is AB.

Each of the three types of Micro USB’s mentioned above have on-the-go features since these are pretty much portable and so are most of the devices that they are used on.

Uses of Micro USB

The micro USBs are power packed little devices that make connections easier. And they are used widely for a plethora of electronic devices. As already discussed, micro USBs are pretty effective in establishing connections between computers and other devices. Some of these interfaces include the following:
