We have a product X, that costs $250
We are going to reduce the cost of one of the components from $35 to $9
So "we should be able to reduce the total cost to $100"
That does not compute.
I'm just guessing here. But at this end of the market, most of the costs involve packaging and peripherals. So by using a 'single chip' computer, they are eliminating the need to stuff a Raspberry Pi into the case along with the interconnections to the camera h/w. Smaller package and a single board that can be machine stuffed as opposed to manual assembly steps.
