Micro Usb will gradually withdraw from the mainstream application market
Micro Usb will gradually withdraw from the mainstream application market. Take a look at the data interfaces of the mobile devices of your friends. It is mainly divided into two camps, an Android TYPE C and an Apple USB lightning. Now the Type-C interface has become a trend. This trend, the application of Micro Usb is becoming less and less, but the opponent is too strong. Let us walk into the world of Micro USB! Nevertheless, Sinodec Industrial Co., LTD., as a Chinese manufacturer
specializing in the production of USB cable, TWS bluetooth earphone and usb wall charger, has been providing various mobile phone peripheral products.
Micro USB is a portable version of the USB 2.0 standard, which is smaller than the Mini USB interface currently used in some mobile phones. Micro-USB is the next-generation specification of Mini-USB. It was established in 2007 by the USB Implementers Forum (USB-IF) of the USB Standardization Organization. It was completed on January 4, 2005. Micro-USB supports OTG. Like Mini-USB, it is also 5pin. The definition of Micro series includes the Micro-B series slot used by standard devices; the Micro-AB slot used by OTG devices; Micro-A and Micro-B plugs, as well as cables, the uniqueness of the Micro series is that they contain a stainless steel housing, which is not a problem for ten thousand times of insertion and removal. Learn the rise and fall from history, let’s take a look at the development history of MicroUSB In June 2004, major global mobile network operators including Vodafone, Orange, T-Mobile, O2, Spain’s Telefonica, Telecom Italia Mobile and Japan’s NTT DoCoMo, as well as major mobile network operators such as Nokia, Samsung, Motorola, Sony Ericsson and LG Mobile phone manufacturers established the Open Mobile Terminal Platform (OMTP) organization. In September 2007, OMTP announced the global unified mobile phone charger interface standard as Micro USB. The new Micro USB specification supports USB technology on mobile devices such as mobile phones. And it is ready for smaller and more compact portable devices in the future. Various portable devices such as mobile phones, MP4s, and digital cameras can be interconnected and communicated without PC transfer. In the future, mobile phones produced by these manufacturers We will devote ourselves to adopting the Micro USB standard and strive to make it a unified charging interface for future mobile phones. The use of the Micro USB interface enables charging, audio and data connections with one interface. What is MicroUSB On the other hand, the conclusion of this agreement is actually the result of the European Union’s advocacy. The European Union’s WEEE department requires manufacturers of handheld devices to be responsible for the waste and pollution caused by differences in interfaces, and hopes that the agreement on a unified interface can reduce this waste. The European Union also recommends that new phones should be packaged because people already have Micro USB chargers, so the charger can be omitted. This will not only reduce waste, but also reduce packaging and transportation costs. In addition, an interface can be used for charging and data. Transmission can simplify various operations, which is also a good thing for users.
Micro USB mobile phone interface The universal charger interface standard officially implemented in China on June 14, 2007 clearly stipulates the overall structure of the charger and the interface on the side of the charger. The most widely used USB A interface can be used to solve the problem of universal chargers and The mobile phone can be easily connected to the computer to realize charging or data transmission. The essence of this standard requirement is "a USB interface is installed in the transformer". The mobile phone charger is changed to a USB data cable and a USB socket The charger and the charger socket can no longer be the standard configuration of the mobile phone. You only need the USB data cable or you can charge directly from the PC interface. There is no relevant standard requirement for the interface on the side of the mobile phone. What is MicroUSB? USB is equivalent to Mini-USB. It has advantages in terms of size, electrical characteristics and plug-in times. Therefore, the Micro-USB interface will be the mainstream of major mobile phones and small electronic devices before 2015.
Micro USB is a mobile phone charger standard, and its main advantages are also many Micro-USB connectors are smaller than standard USB and Mini-USB connectors, saving space, With up to 10,000 plug life and strength, The Micro-USB standard supports the current USB OTG function, that is, in the absence of a host (such as a personal computer), data transmission between portable devices can be directly realized. Compatible with USB1.1 (low speed: 1.5Mb/s, full speed: 12Mb/s) and USB 2.0 (high speed: 480Mb/s), Provide data transmission and charging at the same time, It is especially suitable for high-speed (HS) or higher rate data transmission. It is the best choice for connecting small devices (such as mobile phones, PDAs, digital cameras, digital camcorders and portable digital players, etc.).
Why is it so good to be eliminated? In the early years, when Android smartphones first became popular, almost all the charging ports of Android phones used Micro USB ports. Until now, although mobile phones and other mobile devices have been updated very quickly, there are still many Mobile devices such as mobile phones, smart bracelets, and Bluetooth headsets all use such charging ports, and they are also widely used. In the past two years, the new mobile phones have begun to abandon the Micro USB port and choose to use it. It’s the Type-C interface, so why do mobile phones now suddenly switch to the Type-C interface? The USB Type-C advantage can be a few streets away from Micro Usb, and entering the twilight period is an inevitable result. 1. Supporting high-current and high-voltage charging will help improve the charging speed. It can be said that the Type-C interface is born for fast charging technology. In the future, there will be more and more fast charging technologies for the USB Type-C interface. 2. It supports two-way power supply. The USB Typc-C interface can not only charge the device itself, but also supply power to the external device (so we can realize serial charging, use a USB Typc-C interface cable to connect different devices in series ) 3. Strong expansion capability, USB Type-C can transmit audio and video signals, then it can be expanded to a variety of audio and video output interfaces, such as HDMI, DVI, VGA interface (in short, it can be used as HDMI, DVI, VGA interface So, as long as there is a USB Type-C interface cable, there is no need to buy some HDMI, DVI, VGA interface cables).
