The micro USB technology was developed by the USB Implementers Forum, Inc. (USB-IF), an independent non-profit group that works to advance USB technology. Nokia is one of many companies that will be using the micro USB specification in its upcoming products.

Both are smaller in size than the standard USB, with mini USB predating the micro USB. Both also have five pins, as opposed to four on the standard: one for power, two for data, one for ground, and one for ID. The ID pin is typically of no use in mini USB connectors.

Although one end, the part that connects to the computer, is pretty standard, there are multiple types of connectors on the other end. The most prevalent nowadays are the micro and mini connectors. The main difference between micro and mini USB connectors is their size.

Mini USB vs Micro USB. The Universal Serial Bus, more commonly known as USB, has changed the way peripherals connect to computers by creating a single common interface, which reduced the types of ports on our computers.

For other uses, see USB (disambiguation). USB, short for Universal Serial Bus, is an industry standard initially developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices.

Another benefit to this new connector type is that the micro USB specification will support the USB OTG supplement, a technology that was invented to meet the need for portable devices to communicate directly with each other without the assistance of a computer.

USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power.

Key difference: Mini USB predates the micro USB and both have five pins. However, mini USB has a life cycle of 5,000 connects and disconnects, while, micro USB has a life cycle of at least 10,000 connects and disconnects. Also, micro USB is smaller than mini USB.

When compared to the mini USB, the micro USB offers many advantages. The most obvious benefit to this new technology is its smaller size. As cell phones and PDAs become thinner and lighter, consumers are frequently finding the mini USB connector is simply too large for practical use.
