USB connected sensor dev board

We have a need to add a variety of sensors including in some cases video snaps/streaming. In our case, we are now testing the MT300N and will prefer not to have to take it apart to add such functionality. Instead, I’d like to find an external dev board that would allow optionally adding such capabilities when we need them by simply connecting to the USB port.

I’ve looked on the net but am not finding much information from others using these devices. I know the MT300N has GPIO ports which I suppose could also work but would mean having to take the device apart to solder pins and drill a hole. I see the domino hardware being sold but am not clear if that could work either via GPIO or USB.

Maybe someone here can share one or more links to projects which use this or similar device.
