USB is "Universal Serial Bus" and the Chinese name is Universal Serial Bus. This is a new interface technology that has been widely applied in the PC field in recent years. The Cheap usb connector interface features faster transfer speeds, hot swapping, and connectivity to multiple devices. It has been widely adopted in various types of external devices. There are currently three USB interfaces: USB1.1 and USB2.0, and usb3.0 that has appeared in recent years. In theory, the transmission speed of USB1.1 can reach 12Mbps/second, while the USB2.0 can reach the speed of 480Mbps/second, and it can be backward compatible with USB1.1.
With the rapid development of computer hardware and the increasing number of peripheral devices, keyboards, mice, modems, printers, and scanners have long been known.

Blind insertion structure design,
The Micro-USB standard supports the current USB OTG function, that is, in the absence of a host (such as a personal computer), data transmission can be directly implemented between portable devices.
Compatible with USB1.1 (low speed: 1.5Mb/s, full speed: 12Mb/s) and USB 2.0 (high speed: 480Mb/s),
Provide data transmission and charging at the same time.
Particularly suitable for high speed (HS) or higher data transmission, it is the best choice for connecting small devices such as mobile phones, PDAs, digital cameras, digital video cameras and portable digital players.http://www.fdragtech.com/
