BEWIN micro3.0 interface

1. OTG is the abbreviation of On-The-Go. It is a technology developed in recent years. It was announced by the USB Implementers Forum on December 18, 2001. It is mainly used for the connection between various devices or mobile devices for data exchange. Especially PDAs, mobile phones, consumer devices. It is inconvenient to change data exchange between up to seven types of memory cards by changing a variety of different types of connectors between devices such as digital cameras, video cameras, and printers.

2. The development of USB technology enables PCs and peripheral devices to connect devices of various data transmission speeds in a simple manner and with moderate manufacturing costs. The above mentioned applications can all be used as PC peripherals via USB bus. Data exchange under the control of the PC. However, this convenient exchange method, once left the PC, can not operate with the USB port between the devices, because there is no slave device that can act as a PC.

3. On-The-Go, that is, the OTG technology is to realize the data transfer between the devices without the Host. For example, the digital camera is directly connected to the printer, and the OTG technology is used to connect the USB ports that the two devices see to print the photos immediately; or the data in the digital camera can be sent to the USB hard disk through the OTG. In the field, there is no need to carry an expensive memory card or carry a portable computer.
