It feels like in an instant, the former king fell into the mortal world. Although he doesn't adapt, this is the world. Micro USB has been further and further away from the mainstream application market. Looking at the data interfaces of your friends' mobile devices, there are mainly two camps, one is the Android TYPE C; An Apple Lightning (although it has already been unified), now the Type-C interface unified interface market has become a trend, and various electronic devices around us, from headphones to phones, have been replaced with Type-C; The former king Micro USB, no matter how hard he tried, couldn't twist his arms and thighs, wasting his strength, but his opponent was too strong; Micro USB has exited the mainstream application market and the era has begun
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, developed by the USB standardization organization USB Implementers Forum (USB-IF) in the United States on January 4, 2007. Micro USB supports OTG and, like Mini USB, is also 5-pin. The definition of the Micro series includes the Micro-B series slots used in standard devices; Micro AB slots used by OTG devices; Micro-A and Micro-B plugs, as well as cables, the unique feature of the Micro series is that they include a stainless steel casing, making it easy to plug and unplug ten thousand times; Once the scenery was boundless
Taking History as a Mirror to Know the Rise and Fall, Let's Take a Look at the Development History of MicroUSB Together
In June 2004, including Vodafone Orange、T-Mobile、O2、 Global major mobile network operators such as Telefonica in Spain, TelecomItaliaMobile in Italy, and NTT DoCoMo in Japan, as well as major mobile phone manufacturers such as Nokia, Samsung, Motorola, Sony Ericsson, and LG, have established the Open Mobile Terminal Platform (OMTP) organization. In September 2007, OMTP announced the globally unified mobile phone charger interface standard as Micro USB. The new Micro USB specification supports USB technology on mobile devices such as smartphones and prepares for smaller and more compact portable devices in the future. Various portable devices such as smartphones, MP4, and digital cameras can be used without the need for additional features. In the case of PC transfer, interconnection and communication will be carried out. In the future, the phones produced by these manufacturers will strive to adopt the Micro USB standard and make it the unified charging interface for future phones, The use of Micro USB interface allows for charging, audio, and data connection through one interface; On the other hand, the achievement of this agreement is actually a result of the EU's advocacy. The EU's WEEE department requires handheld device manufacturers to be responsible for waste and pollution caused by interface differences, and hopes that a unified interface agreement can reduce this waste. The EU also suggests that new phones can be packaged without chargers because people already have Micro USB chargers. This not only reduces waste, but also reduces packaging and transportation costs. In addition, an interface can be used for charging and data transmission, simplifying various operations, which is also a good thing for users
The universal charger interface standard officially implemented in China on June 14, 2007, specifies the overall structure of the charger and the interface on one side of the charger. It adopts the most widely used USB A interface, which can solve the problem of universal charger and facilitate the connection of mobile phones to computers for charging or data transmission. The essence of this standard requirement is to install a USB interface in the transformer. The mobile phone charger is changed to a USB data cable and a charger with a USB socket. The charger socket can no longer be the standard configuration of mobile phones, only a USB data cable is needed, or it can be charged directly from the PC interface. There are no relevant standard requirements for the interface on the mobile phone side; Due to the fact that Micro USB is equivalent to Mini USB, it has advantages in terms of size, electrical characteristics, and plugging times. Therefore, the Micro USB interface was the mainstream of major mobile phones, tablets, and small appliances before 2015
Micro USB is the standard for mobile phone chargers and has many main advantages; Micro USB connectors are smaller than standard USB and Mini USB connectors, saving space and having a lifespan and strength of up to 10000 times of insertion and removal,; The Micro USB standard supports the current OTG function of USB, which allows for direct data transfer between portable devices without a host (such as a personal computer). It is compatible with USB 1.1 (low speed: 1.5Mb/s, full speed: 12Mb/s) and USB 2.0 (high speed: 480Mb/s), while providing data transfer and charging. It is particularly suitable for high-speed (HS) or higher data transfer and is the best choice for connecting small devices (such as mobile phones, PDAs, digital cameras, digital cameras, and portable digital players, etc.)
Why should such excellence be eliminated?
In earlier years, when Android smartphones first became popular, almost all Android phones used the Micro USB interface for charging. Until now, although mobile devices such as smartphones have been updated quickly, there are still low-end elderly phones, smart bracelets, and some low-end Bluetooth earphones that use this charging interface, which is also widely used. In recent years, new phones and electronic products have started to abandon the Micro USB interface and choose to use the Type-C interface. Currently, the most commonly used USB2.0 data cable specifications for consumer electronics/digital products are USB-C to USB-C, and USB-C. B-A to USB-C, The former C-C is commonly used in general mainstream products (such as mobile phones, headphones, speakers, fans, shavers, vacuum cleaners, etc.), while the latter A-C high current fast charging is generally used in private fast charging protocols for mobile phones (such as Huawei 6A super high current fast charging, OPPO 5A super high current fast charging, etc.). With the advancement of technology, we will encounter that every time our phone or computer is updated, our original phone or computer charging cable will be upgraded to support higher charging power. The advantages of USB Type-C can be easily surpassed by Micro USB, and entering the twilight is an inevitable result
1. Support high current and high voltage charging, which helps to improve charging speed. It can be said that the Type-C interface was born for fast charging technology, and there will definitely be more and more fast charging technologies for USB Type-C interfaces in the future.
2. Supports bidirectional power supply, using the USB Type-C interface can charge both the device itself and external devices (this way, we can achieve series charging by connecting different devices in series with a USB Type-C interface cable)
3. Strong scalability, USB Type-C can transmit audio and video signals, so it can be extended to various audio and video output interfaces, such as HDMI, DVI, VGA interfaces (in simple terms, it can be used as HDMI, DVI, VGA interfaces, so as long as there is a USB Type-C interface cable, there is no need to buy some HDMI, DVI, VGA interface cables)
From the high-frequency progress and plans released by many large and medium-sized enterprises, it can be seen that Micro USB interfaces have been completely phased out, and Type C 2.0/3.0/3.1 has been fully popularized in the past two years. The high-end interface of Type C is expected to have a quantity of USB4, TBT3 Thunderbolt 3/TBT4 Thunderbolt 4 in the first half of 2025. We have seen that some cable front end factories have been investing in high-frequency transmission cables in recent years, and many have been gradually launched and applied to various high-speed transmission demand product devices; For example, the supporting products of 20Gbps and 40Gbps, the future connectors belong to the Type C interface
