USB 3.0 A to Micro B Panel Mount CablesĪlso referenced as the SuperSpeed Micro USB B connector, this connector stacks five more pins on the side of the USB 2.0 Micro B connector to achieve the full USB 3.0 standard data transfer speed.

USB 3.0 connectors are often in blue color or with 'SS' logo to help distinguish them from previous generations.

USB 3.0 connector is designed to support 5Gbps bandwidth 'SuperSpeed' data transfer, whereas, lower data rate can be transmitted with backward compatibility to USB 2.0 ports.

However, USB 3.0 Type A processes additional pins that are not in the USB 2.0 A Type. Inheriting the same design to the A-Type connector used in USB 2.0 & USB 1.1 application, USB 3.0 A is also provides a 'downstream' connection that is designed for use only on host controllers and hubs.

USB 2.0 A Female to Crimp Housing Cables.

USB-A socket is designed to provide a 'downstream' connection intended for host controllers and hubs, rarely implemented as an 'upstream' connector on a peripheral device. Also known as USB standard A connector, the USB A connector is primarily be used on host controllers in computers and hubs.
