OTG Full Form

What is the full form of OTG?

The full form of OTG is On-The-Go . OTG is a USB (Universal Serial Bus) standard that allows USB devices to be connected. Without using a computer connection, USB OTG items can connect.

By attaching an OTG link, the central device will be your mobile phone.

OTG rules

  • OTG A-device and OTG B-device, showing which side provides the connection power and which one is the first host.
  • The OTG A-device is a power supplier, and the power consumption is an OTG B-device.
