This article is about the usefulness of the OTG interface. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

OTG interface is used for data exchange between different devices or mobile devices, especially PDA, mobile phones, consumer devices, changing connectors of different systems between devices such as digital cameras, cameras, printers, etc., and the inconvenience of data exchange between as many as 7 kinds of memory cards.

OTG is mainly used in the connection between different devices or mobile devices for data exchange.

Especially PDA, mobile phone, consumer equipment. Change the inconvenience of data exchange between different types of connectors between digital cameras, cameras, printers and other devices, as many as 7 kinds of memory cards.

With the development of USB technology, PC and peripheral devices can connect all kinds of devices together through a simple way and moderate manufacturing cost. the applications mentioned above can exchange data through USB bus as the periphery of PC and under the control of PC.

USB was born to simplify the connection between computers and their peripherals.

First used in the keyboard and mouse, the application of USB has crossed from PC peripherals to the field of consumer electronic products and communication electronic products, the most prominent application is in consumer electronic products such as digital cameras.
