USB connector

USB connectors
To understand the usb interface, you must first understand its concept. In English, usb is the abbreviation of Universal Serial Bus, translated into Chinese is the meaning of "universal serial bus". It is not a new bus standard, but a new interface technology for PC applications. In 1995, the usb interface was already used on the PC, but due to the lack of software and hardware support, the USB ports of these PCs were idle. Until 1998, with Microsoft's built-in support module for USB interface in Windows 98, and the increasing number of USB devices, the USB interface gradually entered the practical stage.
Micro USB B type
USB uses a 4-pin plug as a standard plug. With this standard plug, all peripherals can be connected in a daisy chain without losing bandwidth. The USB standard divides USB into five parts: controllers, controller drivers, USB chip drivers, USB devices, and client drivers for different USB devices.

USB requires support from the host hardware, operating system, and peripherals to work. At present, the motherboard generally adopts a control chipset that supports USB functions, and also has a USB interface slot. Windows 98 and above have built-in support for the USB interface (but Windows NT does not yet support USB). At present, there are many USB peripherals such as digital cameras, digital speakers, scanners, keyboards, and mice.
With the popularity of a large number of USB-enabled PCs, USB has gradually become the standard interface for PCs. The latest PCs support almost 100% of USB, and devices that use USB interfaces are also growing at an alarming rate. Currently we are using the USB1.1 standard interface, which has a transmission speed of 12Mbps.
USB 2.0 standard
The seven vendors, COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC, and PHILIPS, have jointly developed the USB 2.0 interface standard. USB 2.0 increases the data transfer speed between devices to 480Mbps, which is about 40 times faster than the USB 1.1 standard. The biggest benefit for users is that they can use more efficient external devices and have multiple speeds. Peripherals can be connected to USB 2.0 lines, unlike the USB 1.1 era, because high bandwidth allows more devices to worry about bottlenecks during data transmission. USB 2.0 can use the same specifications of the cable in the original USB definition. The specifications of the connector are also the same. Under the premise of high speed, the excellent features of USB 1.1 are maintained, and backward compatibility is also guaranteed.

After reading the above, you should have a basic understanding of the usb interface connector related knowledge, and more related to the usb interface, Konnra Electronics engineers will continue to archive for you.
