Micro-USB

From Wikipedia, the free encyclopedia

Micro-USB is a connector technology announced by the USB Implementers Forum (USB-IF) on January 4, 2007.[1] It is intended to replace the Mini-USB plugs used in many new smartphones and PDAs. The Micro-USB plug is rated for 10,000 connect-disconnect cycles. As early as March of 2007 Motorola has begun to ship Micro-USB enabled devices. The H800 Bluetooth headset comes with a switched EPS with a Micro-USB as well as a mini-USB to Micro-USB connector adapter (shown in Micro-USB plug 1 & 2)

The Micro-USB connector is about half the height of the mini-USB connector in wide spread use today but sports a similar width. The major difference between the mini and Micro USB connectors appears to be the addition of a similar resistance system (seen in image labeled Micro-USB Plug 2 below) to the Motorola connector in use by their headsets and cell phones prior to Motorola's adoption of USB.
