How does the USB interface connector work?

USB is an external bus standard used to regulate the connection and communication between computers and external devices.USB interface is plug-and-play and hot-swappable.USB interface can be connected to 127 kinds of peripherals, such as mice and keyboards, etc. USB was launched in 1996 by Intel and other companies at the end of 1994, and it has successfully replaced the serial port and parallel port, and has become the must-have interface for today's computers and a large number of smart devices. The USB version has gone through many years of development and has now evolved into version 3.0. For most engineers, the main obstacles to develop USB2.0 interface products are: to face the complexity of the USB2.0 protocol, write their own USB device drivers, and be familiar with microcontroller programming. This requires not only considerable experience in VC programming, but also the ability to write hardware (firmware) programs for USB interfaces. So most people give up on developing their own USB products. the USB20D module can be regarded as a USB2.0 protocol converter, which converts a computer's USB2.0 interface into a transparent parallel bus, just like a microcontroller bus. Thus the design of a USB2.0 product can be completed in a few days.-2、About Evergrande Electronic Products Network platform related to the introduction and sales of products briefly: Evergrande Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
