The project Ara could be launched in different sizes, ranging from a smaller six-module option to a large-screened model with more modules. The medium “Ara” prototype is inline with an iPhone or Samsung Galaxy S5.
To build a large ecosystem of hardware modules the company is betting big on creativity of thousands of developer. And if everything goes well, then an entry-level phone with basic functions would cost just $50 (Rs 3000) to make.
