What is a Micro USB Connector?

Micro USB Interface Types

The Micro USB is a popular and versatile I/O connector and is currently the smallest form factor available in the USB range, almost 40% smaller than a USB Type C equivalent.

Micro USB connectors are made up of five contacts, with its tiny form factor enabling manufacturers to produce slimmer and more compact devices. Rated to 10,000 mating cycles as standard, it is a very attractive proposition when considering USB due to a great mix of price and performance.

The table below shows compatible mating configurations between Micro USB interface types. There are also Micro USB 3.0 'SuperSpeed' connectors which have an additional 5 pins and difference interface shapes. These will also accept Micro USB 2.0 plugs depending on configuration, but will only run USB 2.0 specification.  GCT no longer produce Micro USB 3.0 connectors as the format has been superseded by USB-C.
