What is the OTG adapter?
Most smartphones and tablets now support OTG. The data interfaces of many of our smartphones and tablets are Micro USB interfaces, which are mainly used for charging and connecting computers for data transmission in mobile phones and tablets. Just connect the mobile phone or tablet to a USB device through the OTG adapter , such as a USB flash drive or a 3G network card.
OTG adapter classification:
Generally, there are two kinds of OTG adapter , one is that it needs to be connected to the power supply, and the other is that there is no need to connect the power supply, but their functions are the same, generally used as an external device for connecting USB, such as a printer, camera. For example, if our mobile phone supports OTG function, what if we want to play movies or music in a USB flash drive? The general user can only transfer the files on the U disk to the mobile phone through the computer to play, but as long as the OTG adapter is used, we can directly play the files on the U disk on the mobile phone.
The role of OTG:
It is to realize the data transfer between mobile devices without a computer. Equivalent to two mobile devices connected by a single wire, through the OTG line, the device can be directly connected for data transfer and printing operations. No need to bring a memory card or computer to transfer. The most common is that the mobile phone expands the mobile device function by connecting a USB device such as a USB flash drive through an OTG cable.
