What is the difference between decomposing a micro USB motherboard and a mini USB motherboard


The similarity between the mini USB motherboard and the micro USB motherboard is that both belong to the USB motherboard of electronic components and are commonly used around us, especially in products related to mobile phones, computers, headphones, and audio systems. And while there are many similarities, there are also many differences between the mini USB motherboard and the micro USB motherboard. Below, the editor will take you to see what is the difference between the mini USB motherboard and the micro USB motherboard!

1. The definition of micro USB mother and mini USB mother is different. Micro USB mother is a portable version of the USB 2.0 mother standard, smaller than the mini USB mother used in some mobile phones. Micro USB mother is the next generation specification of mini USB mother. The micro USB motherboard supports OTG and, like the mini USB motherboard, is also 5pin. The definition of the micro series includes the micro b series slots used by standard devices, micro a and micro b plugs, micro ab slots used by OTG devices, and cables. The unique feature of the micro series sockets is that they include a stainless steel casing, and it is not a problem to plug and unplug them ten thousand times.

Mini USB Master: Also known as Mini USB Master, it is a standard of USB Master Interface. The Chinese meaning of USB is "Universal Serial Bus", which is a technology developed for transmitting data between PC and digital devices. Standard USB sockets, mini USB sockets, and micro USB sockets are currently the most common USB sockets. Compared to the standard USB motherboard, the mini USB is smaller. Mini USB sockets are divided into type A, type B, and type AB. The difference between the micro USB motherboard AB type is that the mini USB B-type 5pin interface can be said to be the most common socket interface at present. This socket interface is winning the favor of many buyers due to its excellent anti misinsertion performance and relatively small size. Except for the 4th pin, the mini USB has the same interface functions as the standard USB. The 4th stitch becomes the ID and is connected to the 5th stitch on mini-a. It can be suspended in the air or connected to the 5th stitch on mini-b.

OTG is the abbreviation for On The Go, which means that OTG technology achieves data transfer between devices without a host. Mainly used for connecting various devices or mobile devices for data exchange.

2. Development history of micro usb master and mini usb master In June 2004, major Mobile network operator in the world, such as O2, Telefonica in Spain, Vodafone, Orange, T-Mobile, Telecom Italia and NTT DoCoMo in Japan, as well as major mobile phone manufacturers, such as Nokia, Samsung, Motorola, Sony Ericsson and LG, established open mobile terminal platform organizations.

In September 2007, OMTP announced the globally unified interface standard for mobile phone chargers as the micro USB motherboard. The new micro USB motherboard specification supports USB technology on mobile devices such as smartphones, and is ready for smaller and more compact portable devices in the future. In the future, these manufacturers will strive to adopt the micro USB motherboard standard for their phones, making it the unified charging socket interface for future phones. The micro USB motherboard interface can be used for charging, audio, and data connection with just one interface.

On October 26, 2009, at the ITU ITU-T Fifth Research Group (SG5) plenary meeting held in Geneva, Switzerland, the framework standard for "Power Adapters and Chargers for General Mobile Terminals and Other ICT Devices" was discussed and approved, and an application was made to enter the approval process. This actually means that the global standard for mobile phone chargers will be unified. It is estimated that the new standard charger can reduce energy consumption by half, and will reduce 51000 tons of waste generated by discarded chargers and 13.6 million tons of greenhouse gas emissions annually. Most importantly, we don't need to have two chargers at home and in the office anymore.

The universal charger interface standard specifies the overall structure of the charger and the interface on one side of the charger, which was officially implemented on June 14, 2007. It adopts the most widely used A-type USB motherboard, which can not only solve the problem of universal charger, but also facilitate the connection of mobile phones to computers, enabling charging or data transmission. There are no relevant standard requirements for the interface on one side of the phone.

3. Advantages of micro USB motherboard and mini USB motherboard: The socket of micro USB is more space saving, smaller, and has a plug and unplug life of up to 10000 times compared to standard USB motherboards and mini USB motherboards, as well as a blind plug structure design. The standard micro USB motherboard supports the current USB OTG function, which allows for direct data transfer between portable devices when there is no host. It is compatible with the USB 1.1 motherboard and also provides data transfer and charging, making it the best choice for connecting small electronic devices. At the same time, it can also provide convenience for the car, only requiring a USB car charger and a micro USB data cable for emergency phone charging. And in high-end cars, there is a 5V output interface directly connected to a micro USB cable to charge the phone. The versatility of micro USB is wide, suitable for convenience.

The micro USB motherboard is equivalent to the mini USB motherboard, and has significant advantages in terms of volume, electrical characteristics, and plugging times. Therefore, the micro USB motherboard will become the mainstream. Through the above explanation, we can see that the market prospects of the USB motherboard are very good.
