The micro USB connector is smaller than the standard USB and Mini USB connectors, saving space, and the plug-in life and strength are up to 10000 times. It belongs to the blind plug-in structure design. The micro USB standard supports the OTG function of the current USB, that is, the portable device can directly realize data transmission without a host (such as a personal computer), and is compatible with USB1.1 (low speed: 1.5mb/s, full speed: 12MB/s) and USB2.0 (high speed: 480MB/s).
