Power consumption is one deciding factor. If your application is battery powered, perhaps a data-gathering node in a remote location, then power consumption becomes a critical factor. If the unit is supplemented by solar power, the Model A’s power requirements are more easily satisfied.
Model B
The main advantage of the Model B is its networking capability. Networking today is so often taken for granted. Yet it remains a powerful way to integrate a larger system of components
