What Is Mini USB?

Mini USB is the abbreviation of Mini Universal Serial Bus which is a USB interface standard. It is a technology developed for transferring data between PC and digital devices.

mini USB A and mini USB B

Mini USB is divided into A-type, B-type and AB-type. Mini B-type 5 Pin is the most common type of interface. This type of interface is superior in anti-missing performance and size, so it is winning a lot. Venders favor card readers with this interface. This preference also applies to MP3 players, digital cameras and mobile hard drives.

The mini USB cable is made of coaxial cable which transfers data and power between two devices. While one end of the mini USB cable is a standard flat-head USB hub, the other end is a much smaller quadrilateral hub suitable for mobile devices.

In addition, some mini USB cables are designed to be used only with certain brands of mobile devices which can limit charging or transferring data from a computer or standalone charger by including additional internal pins that run unnecessary voltages.
