There are several types of USB connectors, including:
- Type-A: The most commonly used USB connector, found on one end of a standard USB cable. It is rectangular in shape and typically connects to a computer or other host device.
- Type-B: Less common than Type-A, Type-B connectors are typically found on devices such as printers and external hard drives. They are square in shape and typically connect to a Type-A connector.
- Type-C: The newest USB connector type, Type-C is reversible and can be inserted into a port in either orientation. It is becoming increasingly common on devices such as smartphones and laptops.
- Micro-B: A smaller version of the Type-B connector, Micro-B is commonly found on devices such as smartphones and tablets.
- Mini-B: Another smaller version of the Type-B connector, Mini-B is less common than Micro-B and is being phased out in favor of Micro-B.
- USB 3.0/3.1 Type-A and Type-B connectors are designed in the same shape as USB 2.0 connectors but have additional pins to support faster data transfer speeds.
