USB B-MICRO ADAPTERS
Micro USB is a mini version of the Universal Serial Bus (USB) interface developed to connect compact and mobile devices such as smartphones, MP3 players, GPS devices, photo printers and digital cameras.
Micro USB connectors come in three forms: micro A, micro B and micro USB 3. USB 3 micro is much like micro B, but with an extra pin group on the side for twice the wires, allowing USB 3's higher speed. Like standard USB, the micro versions are plug-and-play.| CaseOnline.com
