What is an Android OTG Device?

For the SmartScope USB Oscilloscope from LabNation to work with Android phones and Tablets they are REQUIRED to support USB OTG (On The Go) functionality.

Simply put, USB OTG (On The Go) enables mobile devices, like smartphones and tablets, the ability to function as a USB Host Device for communication with devices like mice, keyboards, flash drives or other devices provided the host device is capable of providing enough power to run the device connected. Some OTG compatible peripherals can function correctly by using a powered USB hub if the host device doesn’t supply enough power.

We have searched the web for a list of devices that offer OTG functionality,  It is not complete and we have no way of testing every device out there that claims OTG support.  OTG support was introduced in Android v3.2 (Honeycomb), but some manufacturers did not elect to support the feature.

There are Apps that can test a device to see if the required drivers are installed. They can be found by searching for “USB OTG” on the Google Play Store.

Here is a partial list of OTG Supported Devices.   (Unconfirmed by Circuit Specialists)
