The micro USB waterproof motherboard, micro Mike USB motherboard, and the latest USB motherboard Ctype (USB3.1 standard) USB motherboard A-type are our common USB interfaces. Common USB motherboard A-type interfaces are found on desktop and laptop computers! Its characteristics are large interface volume, convenient installation, firmness, not easy to loosen, easy for designers to draw board, and no need to consider too many other electronic components arranged tightly. The USB motherboard B-type is a USB interface that we often see on printers. Its interface surface is a square interface, which has high recognition and is a unified standard for printer interfaces. The Mini Mini USB motherboard interface is an improved model of the regular USB motherboard A-type interface, with a volume less than half of that of the A-type USB motherboard. The appearance of this Mini USB motherboard well adapted to the miniaturization trend of digital electronic devices at that time,

The micro USB2.0 specification has evolved from the USB1.1 specification. Its transmission rate has reached 480Mbps, which is equivalent to 60MB/s in MB, which is sufficient to meet the speed requirements of most peripherals. The Enhanced Host Controller Interface (EHCI) in micro waterproof USB 2.0 defines an architecture that is compatible with USB 1.1. It can use the micro waterproof USB 2.0 driver to drive USB 1.1 devices. That is to say, all devices that support USB 1.1 can be used directly on the micro USB 2.0 interface without worrying about compatibility issues, and accessories such as USB cables, plugs, etc. can also be used directly. Currently, most computers sold use the USB2.0 specification. Firstly, USB waterproof motherboards can be generally divided into USB-AB type motherboards, USB-B type motherboards, MINI mini motherboards micro USB waterproof motherboards, micro Mike USB motherboards, and the latest USB motherboard Ctype (USB3.1 standard) USB motherboard A-type is our common USB interface. What is commonly seen on desktop computers and notebook computers is the ordinary USB motherboard A-type interface! Its characteristics are large interface volume, convenient installation, firmness, not easy to loosen, easy for designers to draw board, and no need to consider too many other electronic components arranged tightly. The USB motherboard B-type is a USB interface that we often see on printers. Its interface surface is a square interface, which has high recognition and is a unified standard for printer interfaces. The Mini Mini USB motherboard interface is an improved model of the regular USB motherboard A-type interface, with a volume less than half of that of the A-type USB motherboard. The emergence of this Mini USB motherboard well adapted to the miniaturization trend of digital electronic devices at that time, such as MP3, which used the Mini USB interface for charging and data transmission. The micro Mike USB motherboard is currently the most widely used USB interface on mobile devices (such as mobile phones), with a volume less than half that of the MINI mini USB motherboard interface, making it difficult to align it with the circuit board simply by testing! The emergence of microUSB motherboards was developed due to the industry's demand for micro device interfaces. The latest USB motherboard C-type is the latest USB motherboard standard. For example, the latest 12 inch Apple laptops are equipped with a USB motherboard C-type interface, also known as the USB3.1 interface! The above is only for distinguishing and distinguishing the types of USB interfaces. For example, in terms of packaging specifications, each micro waterproof USB motherboard has a variety of circuit board packaging specifications, which is difficult to describe here.
