What is a mini USB cable?

The USB-Mini was used for connecting mobile devices including MP3 players and cameras, and is a much smaller connection, thus allowing smaller devices to connect, the small USB socket found on digital cameras, external hard drives, USB hubs, and other equipment. Mini USB is much smaller than USB Type A and B but twice as thick as Micro USB.

One drawback to the B-style connector is its size, which measures almost a half inch on each side. This made the B-style interface unsuitable for many compact personal electronic devices. As a result, many device manufacturers began miniaturizing USB connectors with this Mini-B.

1. The USB-IF recognizes this 5-pin USB Mini-B connector.

2. This connector is relatively small, about two-thirds the width of an A-style connector.

Definition of Mini USB

First, you need to understand the definition of a mini USB. Mini USB is the abbreviation of “Mini Universal Serial Bus (USB)”. USB is a technology designed to transfer data and files between computers and electronics. Of course, Mini USB is a smaller version of USB. It is a small USB socket found on a variety of devices.

Mini USB was one of the earliest USB connection types developed in the early 2000s. Mini USB was once a groundbreaking idea and a highly effective technology for a world that has come to love compact digital devices such as mobile devices.

As technology advances, only a few devices currently come with mini USB connectors. While Mini USB is still in use, it’s become so rare that buying off-the-shelf retrofit cables from small retailers may not be an option. You can try to buy a mini USB connector directly from us.

Mini USB interface, this interface is ladder-shaped, small in size, and has different lengths at both ends to prevent mis-plugging. Although Micro USB once occupied the mainstream in the mobile phone market, Mini USB itself has a large market. For example, Mini USB can be seen in small electronic devices such as MP3, etc.

1. Support OTG, allowing data transmission between devices without a host.

2. The interface size is small, and the connection is relatively firm and not easy to loosen.

3. It can not only transmit data but also charge mobile devices.

Interface definition

Mini USB A, and B connectors and their contacts (not drawn to scale) Mini USB connector contact functions
1—VBUS (4.4–5.25 V)
2—D−
3—D+
4—ID
5—Ground
The ID foot is only used in the OTG function. Because the mini USB interface is divided into mini-A, B, and AB interfaces. If your system is only used as a slave, then use the B interface. The system controller will judge the level of the ID pin to determine what kind of device is plugged in. If it is high-voltage, then the B connector is plugged in. At this time, the system will do the slave mode, if the ID is low, the A interface is inserted, and then the system will use the HNP dialogue protocol to decide which one will be the master and which one will be the slave.
OTG is the abbreviation of On-The-Go, that is, OTG technology is to realize data transmission between slave devices without a Host. It is mainly used for connection between various devices or mobile devices for data exchange. For example, a digital camera is directly connected to a printer, and the USB port between the two devices is connected through OTG technology, and the photos taken are immediately printed; the data in the digital camera can also be sent to a mobile hard disk with a USB interface through OTG. , there is no need to carry expensive memory cards or carry a portable computer for field operations.
Except for pin 4, mini USB interface functions are the same as standard USB. Pin 4 becomes the ID and is connected to pin 5 on mini-A. It can be left floating or connected to pin 5 on mini-B.
