Micro USB development history
In June 2004, the world's major mobile network operators including Vodafone, Orange, T-Mobile, O2, Spain's Telefonica, Telecom Italia Mobile and Japan's NTT DoCoMo and NOIN, as well as Nokia, Samsung, Motorola, Sony Ericsson and LG Other major mobile phone manufacturers have established an OpenMobile Terminal Platform (OMTP) organization. In September 2007, OMTP announced that the global unified mobile phone charger interface standard is Micro USB. The new Micro USB specification supports USB technology on mobile devices such as mobile phones, and 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 going through a PC. In the future, the mobile phones produced by these manufacturers will focus on 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 one interface to perform charging, audio and data connections.
On the other hand, the conclusion of this agreement is also the result of the EU's active promotion. The EU WEEE department requires handheld device manufacturers to be responsible for the waste and pollution caused by the interface differences, and hopes that the unified interface protocol can reduce this waste. The EU also suggested that the new phone can save the charger because it has a Micro USB charger. This will not only reduce waste, but also reduce packaging and shipping costs. In addition, an interface can be used for charging and data transmission, which can simplify various operations and is also a good thing for users.
