Micro USB is a type of connector that was created in order to replace the traditional USB connector. It’s smaller and it also has a reversible design, meaning there are no wrong ways to insert it. The micro USB connector can be found on many different devices, including smartphones, cameras, car stereos, TVs, and more! The Micro-USB interface was introduced as a new standard by the Universal Serial Bus Implementers Forum (USB IF) group of companies in 2009. http://www.cableconnector.net/usb-cable/micro-usb-cable/
