With an inexpensive USB OTG adapter, you can connect things like keyboards, USB hard drives, and even gaming controllers to your Android phone or tablet.
With the iPadCamera Connection Kit allowing users to connect a variety of unexpected USB devices (like a MIDI keyboard) to their iPads, the next logical question was, “Is there something similar for Android?”
Although it’s not advertised or sold by any of the big Android phone manufacturers, the solution is a cheap cable called a USB On-The-Go adapter.
USB On-The-Go (Amazon link), or USB OTG, is essentially a female USB port that plugs into the Micro-USB port of a phone or tablet, allowing you to connect devices that use a standard USB 2.0 or 3.0 connection. In a nutshell, the adapter allows the Android device to be a “USB host,” powering and communicating with the connected device.
