Today, everyone knows what USB (USB). It is a small connector on the motherboard of a computer, laptop, printer, mobile phone, camera, player, Yes, almost everywhere. It can be used to connect to the device is not only the battery charger and the drive, but anything, even a foot warmer.

What is USB? It is a way of connecting and transferring data between different electronic devices (the so-called UNIVERSAL SERIAL BUS).

History and main principles of the standard USB

The First standards for USB was developed by a group of the largest manufacturers of electronic equipment and software, like Intel, Microsoft, IBM, Philips, NEC and others. It was originally an open standard for manufacturers of any equipment and software.

The Basic principle of this standard is the versatility. It was assumed that the universal connector will replace all the existing narrowly-specific interface connectors of additional external devices of the computer and will lead the development and production of non-standard devices and modules.

The Presence of a power line at 5 Volts let some of the connected devices do not have external power source.

Ease of use suggested the presence of possible hot-plugging (or “plug and play”) that do not require the installation of specific cards, drivers, and even turn off your PC.

Another very important principle of the standard is the ability of some devices to act as nodes to connect more devices by performing the so-called function of the hub. For example, the ability to connect the camera to some printers, the mouse is on that keyboard, etc.

Why you need a USB

YUSB - is primarily the ability to connect to a personal computer various electronic devices for data transfer and synchronization (keyboards, mice, flash drives, phones, iPods, cameras, cameras, printers, scanners, external storage media and CD-ROM, and much more.)

Since its interface contains the line supply 5 Volt, it primarily provides the ability to specific connected devices to abandon the external sources of energy, and secondly - to use USB not for its intended purpose, and for charging mobile phones, music players, mobile speaker with battery, flashlights, etc.

There was also a separate category of USB devices like lamps, fans, self-heating cups using the port only as a power source.

USB

Today there are 3 versions.

micro mini usb

USB 1.1 is almost not applied because of the low speed conveying information – not more than 12 Mbit/s. In the modern world is used purely for compatibility.

USB 2.0 is currently the leader. Guarantees speed of data transmission up to 30 MB/s For most modern devices (except the external Winchester) this speed is enough.

USB 3.0 belongs to the last generation provides the speed of data transmission up to 500 MB/s. Given that the processing speed of modern hard disks below three times, this version has enough clearance for the speed to remain relevant and in demand.

USB 3.0 and 2.0: types

USB 2.0 type a the most popular. Most of the devices (keyboards, mice, flash drives and similar) are equipped with data port. It was created in the mid-nineties. Reliability, which provides the opportunity to meet quite a large number of connections and remain whole and healthy - that's the main advantage of this port. In the connector there is protection from wrong connection. But the dimensions do not allow to use it for portable devices.

usb 2 0

USB 2.0 type B are less popular. The classic type B – the only one in the entire range has a square shape. Because of the relatively large size it is used in different stationary systems (scanners, printers, and other devices of a different type).

The Emergence of a huge number of small portable devices contributed to the fact that the USB connectors have miniaturepoodles and turned into a mini version 2.0 B. other device brought the proliferation of portable hard drives and PDAs. Mini USB, type B has five contacts, one of whom was not involved. However, despite the advantages of miniaturization, the disadvantage of this connector is the low reliability. Also there is a Mini USB type A. It is not actually used differs from B only in the form.

Micro USB Connector B is essentially the same as Mini USB B, but subjected to improvement and characterized by a relatively small size. Thanks to the sizes it is ideal for use in modern thin gadgets. The streamlined mounting of the plug does not allow it to become loose and fall out of the nest.

micro usb b

Since the beginning of 2011 Micro USB B adopted as a universal standard for chargers of most tablets, mobile phones and other miniature devices. There is also a type A. it Occurs quite rarely and differs only in rectangular shape.

The Most up-to-date USB 3.0 provides the abilityto achieve high speed data transport. Additional contacts provide an opportunity to accelerate the process of information transfer that led to the modernization of most devices, third edition. External USB But the changes affected only the color of the core – now it's blue. Otherwise compatibility USB 3.0 and USB 2.0 AND remains unchanged. This means that the modules are cross compatible.

USB 3.0 type B intended for use in a remote volume or external devices with high capacity and performance, as well as in some stationary hard drives. In many ways, the port unlike its predecessor, though it has inherited the traditional features common features Micro USB 2.0. Compact, reliable, high-quality connection, it allows for much faster to transfer the necessary information. Connector equipped with ultra speed external hard drives and SSD.

Also, the last time there was a subspecies of the USB, as Micro 3.0 or 3.1 type C. the pin Configuration is similar to type B but differs in the form of the connection.

People are occasionally confused in connectors USB Mini and Micro, in fact, they really are very similar. However, the main difference is that Mini USB is a little larger than, and Micro equipped with small clips on the back side. Otherwise they are identical.

Why is the Micro USB

Micro USB Connector is a small, fairly reliable and currently the most common implementation of the standard.

Thanks to advanced mount with spring-loaded latches holding it firmly in the socket not loose and does not fall out. To date, Micro USB – universal standard for sync cables and chargers for mobile technology and other gadgets most manufacturers in the world. No matter where you were, everywhere the chance to meet a Micro USB cable or similar charger is much higher than any other type of gadget. Rare devices, such as products from Apple, have their own unique connector, unlike this one. However, there are plenty of adapters that allows you to connect to any Apple device Micro USB cable.

Variations of device performance

Depending on manufacturer and purpose, there are several variants of connecting cables with Micro USB. usb adapter

The Manufacturer may vary the length of the cable, the thickness and material of insulation, the presence of the screen, additional cores or ferrite filters at its discretion, and based on the destination of the cable and its value.

First of all, the Micro USB cables with different end caps. On one side of the cable type, and on the other can be type a (standard option and OTG – the so-called mother), and Micro type b (also available in one of two variations), Mini and virtually any of the existing variations of the connector of corresponding standard.

Very rarely possible single specific variation of the use of the Micro USB cable just for power transfer or certain data. This is facilitated by its popularity and availability.

Micro USB Pinout

The Purpose of the wires in the USB cable:

micro usb Pinout

  • Red - VBUS - (+5V Vcc )+5V, 500 mA DC relative to GND.
  • White - D- (-Data).
  • Green - D+ (+Data).
  • Black - GND - - 5V or ground.

The Micro connector, Mini USB has 5 contacts:

  • Red - VBUS.
  • White - D-.
  • Green - D+.
  • ID — connector type B is not used, or is shorted with GND to enable the OTG function.
  • Black-GND.

In some cases, Micro USB cable can include a braid, the shielding or the bare wire (can pripiats to the body of the connector), this cable does not numeroita.

The Variety of USB adapters

USB adapter-the compact device, which converts the standard USB interface of other standard. There are models that convert in the reverse direction.

The Main task of the adapter is compatibility. There is always the possibility of a situation when you need to connect to a computer, smartphone or tablet device with a nonstandard interface or connector. In this situation come to the aid of USB adaptor, types and standards which to date big set.

There is a specific kind of adapter with separate power schemes and the division of channels – USB-hub. It allows you to simultaneously connect several power-hungry devices, sometimes even different types, to one port of your computer, laptop or other mobile device due to the fact that the type A, b, Mini, Micro USB Pinout the same standard.

The Advantages and disadvantages of Micro USB connector

Considering all above, we can sum up: the Micro USB is the logical conclusion of the evolution of the standard.

The advantages are: small size, relative reliability, versatility, and prevalence.

But oddly enough, the main advantage was the main downside. Miniaturization has reduced the reliability of the connector, especially in places of fastening and soldering.

However no matter where you were, find the Micro USB cable to charge your favorite tablet or reset the PC a couple of photos with your phone, it will not be difficult.
