What are the two interfaces of the MICRO USB 3.0 connector?

The kind of mobile hard disk is indeed MICRO USB 3.0 interface (also said miniUSB3.0) USB3.0 compared to 2.0 to add 5 contacts. Because USB3.0 has backward compatibility, can be compatible with 2.0 cable or host, in general A type USB interface can also ensure that the shape of the 2.0 interface does not change to add contacts. However, USB2.0 in the B-type port and microUSB interface size, there is no room to add more contacts, so it is used in the original interface to add structure around the method. In this way, 3.0 cable can be inserted into all interfaces, 2.0 cable only inserted into the corresponding shape of the position, can be used. USB3.0 B-type port shape is close to the number 8, similar to a large and a small two squares stacked into the middle of the larger square is exactly the shape of the usb2.0 B-type port, 2.0 cable can be inserted directly into the top, can be used, but only 2.0 speed only. microUSB3.0 B-type port and microUSB interface size, there is no room to add more contacts in the original interface around the structure of the method is used. The microUSB3.0 interface shape is flat and wide, close to a gap on one side, the gap on the side compatible with the use of microUSB2.0 cable (micro USB3.0 has two types of interfaces, micro-A, micro-B). This also completes the USB3.0 system to ensure the perfect downward, although the width increases, but the thickness of miniUSB3.0 is still Z small USB3.0, in the ultra-thin mobile hard disk, there is still a meaning of existence.-2、About Evergrande Electronic Products Network platform related to the introduction and sales of products briefly: Evergrande Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
