At present, the type of USB interface on the market is complicated, and many users are not sure about their naming. Let’s take a look at the common interface types of USB cable.
1. USB Type-A, this interface is often used for mouse, keyboard, U disk, data cable, etc.
2. USB Type-B, this interface is relatively rare in our daily life, often used in printers, and has a shape and version distinction.
3. USB Type MicroB, this interface is familiar to everyone, is one of the commonly used charging interfaces of previous Android phones and some low-end machines.
4. USB Type-C interface, which is the interface commonly used in some high-end Android phones. Many mobile phones have also removed the headphone jack, allowing it to be charged and function as a headphone jack. And the Type-C interface will also become a unified USB interface in the future.
USB transmission protocol
The USB transfer protocol currently has the 1.0, 2.0, 3.0, 3.1 standard, and 3.1 is the highest transfer rate in the USB interface.
USB Type-A: The transfer protocol is available from USB1.0 to USB3.1.
USB Type-B, USB Type MicroB: The transfer protocol cannot reach the USB3.1 standard.
USB Type-C: Transmission protocols 2.0, 3.0, 3.1 are available, so some phones have a Type-C interface, but it does not mean to support the 3.1 transmission protocol standard. USB3.1+USB Type-c is the best combination at present.
Advantages of the USB Type-C interface
1, can be inserted in the positive and negative.
2, can carry higher data transmission and power transmission.
3, the function is more abundant than the previous interface.
4, USB Type-C can achieve charging, audio output, data transmission, display output and other multi-function, many devices can be used with only one line.
5, USB 3.1 + Type-C can support high current charging, charging faster.
Lightning 3 interface
Apple MacBook’s lightning 3 interface. The transmission rate is more than four times that of the USB 3.1 interface, because the transmission protocol of the lightning interface is an exclusive standard set by Apple and Intel. And USB1.0, 2.0, 3.0, 3.1, are versions of the development developed by the USB Design Institute.
