Understanding USB A and Micro-USB Connectors

• USB stands for "Universal Serial Bus." It was
  created to make the connections between computers
  and outlying devices simpler. Since its
  development in the 1990s, it has become a
  household/office item because of its low cost of
  implementation, ease of use, and, most
  importantly, its compatibility with various
  platforms and operating systems. Very few
  computers nowadays are built without a USB port.
  It is the preferred interface for almost all
  office and home peripherals like modems, hard
  drives, speakers, cameras, etc. These cables were
  first introduced by tech companies to provide a
  uniform connection standard for transferring
  electricity and data.
• Now, there are several types of USB connectors
• USB-A
• USB-B
• USB-C
• USB Micro-A
• USB Micro-B
• USB Mini-B (5-Pin)
• USB Mini-B (4-Pin)
• USB 3.0 A
• USB 3.0 B
• USB 3.0 Micro B
• USB-A to Micro-B
• USB Mini-B (Fuji?)
• Lets learn more about USB-A, USB Micro-A, USB
  Micro-B, and USB-A to Micro-B.

• USB-A
• USB-A is most commonly found on host computers.
  Almost all personal computers and laptops have
  one USB-A port, if not more.
• USB-A cables have a rectangular connector with an
  opening on one side and a plastic wedge on the
  other half. This allows you to connect one
  device. These cables have a flat, rectangular
  interface, which holds the connection in place
  using friction, making it easy for users to
  connect/disconnect. These cables use flat
  contacts instead of round pins, as they can
  handle continuous attachment/removal.
• Now, lets see micro USBs. The smallest type of
  USB cable is called a micro USB cable, which
  comes in two connection types. These come in
  handy when you cannot use mini or standard USB
  connection ports. They provide the same
  performance as their standard-sized counterparts.

• Micro-A USB
• Micro-A USB cables differ from the standard USB
  connection and are most commonly seen in On the
  Go (OTG) devices. You do not require a computer
  to act as a mediator when you build a connection
  between two devices using a Micro-A USB cable.
• These cables come with a rectangular-sized female
  connector. Its identifying marks are a compact
  5-pin design and a white receptacle. Micro-A USB
  cables are compatible with Micro-B USB
  technology.
• Micro-A USB connectors can be found on GPS units,
  digital cameras, and cell phones. These cables
  support a high-speed transfer rate of 480 Mbps.
• Micro-B USB
• Micro-B USB connectors can be found in
  smartphones and other small electronic devices.
  These cables are available with male and female
  connectors, making it easier for you to use
  devices with different connection types.
  Usually, female connectors can be found on
  smartphones, while the cable comes with a male
  connector.
• Micro-B USB connectors are half-hexagonal in
  shape because the connectors and ports have
  tapered edges. These cables consist of a
  black-colored receptacle and a portable 5-pin
  design.

USB Type-A To Micro-USB
The USB-A cables other end is made up of a
Micro-USB A or Micro-USB B connector and thus can
accept either connection. This cable is designed
exclusively for USB On-The-Go devices. These
connectors are identified by their distinct
gray-colored receptacle and compact 5-pin design.
You wont find this on any cable, as it only
exists as a receptacle for On-The-Go devices. The
items that can commonly use this cable are
Bluetooth speakers, e-reader devices, small
gadgets like reading lights, and so on. SF Cable
