Learn About Type A Male-to-Micro-A-Male USB Cables

This micro USB cable has a type A male connector on one end and a micro-A USB male plug on the other end. It will allow you to connect a type A device with a micro-A device, so you can transmit data between them, sync them together, or charge the battery on a portable device. Micro-A is commonly used in smaller hardware such as smartphones, tablets, PDAs, and some digital cameras whereas type A is ubiquitous in most desktop and laptop computers as well as some printers and external hardware.

What are the data transfer speeds of USB?

USB has had three major releases, plus a few minor revisions. Each version features a faster data transmission speed than the one before it. These speeds are listed by the maximum possible transfer limit. In practice, the speeds may be somewhat slower, depending on real-world conditions.

  • USB 1.0: Both the initial release version and USB 1.1 feature speeds of 12Mbps. USB A was released at this time.
  • USB 2.0: USB 2.0 has a maximum possible transfer speed of 480Mbps. The micro-A interface was introduced with this version. Thus, the earliest possible micro-A version is USB 2.0.
  • USB 3.0: USB 3.0 was a major revision to the USB standard. The type A "SuperSpeed" port was introduced around this time, allowing for even faster levels of data bandwidth. The maximum transfer rate of USB 3.0 is 5Gbps.
  • USB 3.1: This is a partial upgrade of USB 3.0. The data transfer rate was increased to 10Gbps.
  • USB 3.2: Another partial revision. The data transfer rate is a maximum of 20Gbps.
Are different USB versions compatible with each other?

That depends on the type of connection. All type A connections are completely interchangeable with each other. A 3.0 male plug will still work in a 2.0 port, and a 2.0 male plug will work in a 3.0 port, although it might only operate at the speed of the slowest version. Micro-A is a bit more complicated. A 2.0 male connector will work with a 3.0 port, but a 3.0 male connector is not compatible with a 2.0 port. Again, it only operates at the speed of the slowest version. Micro-A should connect to any computer or phone that has a standard AB slot. Standard and SuperSpeed micro-B ports are not compatible with micro-A connectors.

What is the maximum length of a USB cable?

Both versions 1.0 and 2.0 allow for a maximum USB cable length of 5 meters, or just over 16 feet, while it can still operate at full speed. USB 3.0 does not necessarily specify a maximum USB cable length, but a copper cable with AWG 26 wires can still operate at full speeds up to a length of around 3 meters or nearly 10 feet.
