A Personal computer to communicate with other devices of the necessary compact enough and high-speed port input/output. At the time this function was performed by the so-called COM port has a number of disadvantages. First of all, developers were not satisfied with its dimensions, the performance faded into the background. Also a good option at the time was the use of LPT, which has remained unchanged until now. This is the place where is connected the printer. Imagine the size the stick it was necessary to create in order to use this connector? Nevertheless, he remained still and has a high performance due to the use of the Protocol parallel data transfer.

mini usbThis task was created so-called mini-USB port that is used when working with compact and small-sized devices. They are equipped with mobile phones, cameras, chargers, dongles, video surveillance systems, etc. due to its small size it is easy to “fit” in the design of these devices and copes with its responsibilities.

According to the principle of the mini USB port is no different from his big “fellow”. It is made from two of the power wires and two designed for data transmission. The wires twisted in twisted pair for mini USBReduce interference when working. With the same purpose they are placed in a special screen. Usually transition the cord has a short length, is designed for the location of the electronic device near the computer. This too has its meaning. The shorter the connection, the more stable the mini USB port mode of data transfer. As the device is working with low voltage circuits, it makes sense the cord is located away from the network or other sources of interference.

The data transfer Protocol is sequential, and the process is controlled by special controller. The performance of this method of communication is enough to ensure stable operation of the electronics.

The power Wires, embedded in a mini USB connection, perform two useful functions:

  • First, they stabilize the process of data transmission. This is because mini usb connectorA magnetic field, which creates a twisted pair with the power source has a constant component. It prevents the penetration of extraneous noise in the “information” wires.
  • Secondly, a mini-USB socket allows “power” low-power device, for example, to charge a mobile phone.

An Alternative to this connection is wireless, for example Bluetooth or a Red Port, but they all lose wireless connection speed and noise immunity.

Quite promising direction in the development of the mini USB connection is the development of new controllers with higher clock frequency. This increases the speed of data transmission. Further miniaturization will depend on the design features of the devices. It should also be noted that the optimum size of the port directly related to the maximum current of the power wires. Depends on maximum power when charging electronic devices.
