USB Type A and Type B Pinout(Male and Female)

USB Type-A is used to make a connection with a PC while Type B is used to connect smaller peripherals. In other words, Type A is a downstream connector, while Type B is an upstream connector.
The USB type A has rectangular, while type B has a square-like shape. Both of them have 4 pins.
Both these USB types differ in purpose and shape, but their pin connections are the same. Pin 1 is dedicated to the supply and pin 4 is for ground connection. Even pin 2 and 3 take the data input in both these types.
The female port has the PINs in descending order, starting from the right-hand side, while the male connector has them in the reverse order. The table below shows the pinout of both the USBs.

USB Mini A and Mini B Pinout

USB Mini was the first improvised version of the normal connectors. This version was launched for both Type A and Type B. It’s a smaller version of Type A and B which was extensively used with old mobile phones. The Mini B connector is more popular than Mini A. The figure below shows the pinout of USB Mini B.
USB Mini B is thinner and more compact than Mini A. Hence it is used for PDAs, digital cameras, etc. Another significant development imposed on Type Mini is that it has an additional pin to support On-the-GO (OTG) connection. Thus it has 5 pins. The pin connections are given in the table below.

USB Micro A and Micro B Pinout

USB Micro is thinner and gives a higher data transfer speed than the USB Mini. It is often used for charging portable devices and comes in two shapes. Micro A is rectangular whereas Type Micro B has a camper shape.
The USB Micro also has 5 pins similar to that of the USB Mini, where the additional pin supports OTG connectivity. The table below shows the pinout of Micro-A and B.
