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

Especially PDAs, mobile phones, and consumer devices. It is inconvenient to change the connectors of various different formats between devices such as digital cameras, camcorders, printers, etc., and exchange data between up to 7 formats of memory cards.

The development of USB technology enables PCs and peripheral devices to connect various devices together in a simple way and at moderate manufacturing costs. The applications we mentioned above can all be used as PC peripherals through the USB bus. Data exchange occurs under PC control.

Origin of OTG development:

Since the USB1.0 specification in 1996, USB-IF (Universal Serial Bus Implementers Forums) has successively announced USB2. 0 and USB OTG and several other specifications, among which the transmission bandwidth of USB2.0 reaches 480Mbps.

USB OTG enables USB devices to get rid of the limitations of the original master-slave architecture and realize an end-to-end transmission mode. With the continuous improvement of USB specifications, the application fields of USB have also been expanded. The original intention of USB was to simplify the connection between computers and their peripherals.

Originally used on keyboards and mice, the application of USB has crossed from PC peripherals to the fields of consumer electronics and communication electronics. The most significant application is in consumer electronics such as digital cameras.
