There are three variables in equation which defines a computer (IT product) selling price: quantity, quantity and quantity.appdev007 wrote:That would make the IO board $175! That seems to be out of proportion to the cost they are building PI model B for.
Most average users will be happy with their Model A, B or B+.appdev007 wrote:I'll put my money on the fact that at least 78% of the people who wanted a model B instead of an A are also going to one a computer module and I/O board. They have to know this and know they are going to sell plenty of them. I wonder what the ratio of private to commercial purchase is for the regular PI boards. This one my tip the scale toward commercial, but I bet not as much as one might think.
The CMIO3 also handles enough power for the CM3. This is like the difference in power requirements going from a B+ to a Pi3B.
What?????handles enough power
As a compute module user, you are expected to roll your own "application board", which should end up costing only a fraction of the IO Board, when you create them in much larger numbers than the IO Board, also because they should only contain the components that are essential for your application, and nothing else.appdev007 wrote: ↑Mon Jul 14, 2014 3:39 pmhttp://www.raspberrypi.org/raspberry-pi ... w-product/

The official page says the module will cost $30 per 100 units, but it doesn't mention the cost of the IO board. Element14 is listing the bundle at $215; so let call the worst case per single unit cost of the module $40. That would make the IO board $175! That seems to be out of proportion to the cost they are building PI model B for. I'm using the model B as an example because it shares components with the IO board (some size of circuit board, RJ-45, USB, ...). I realize the DIM slot, extra pin headers, those big chips in the middle, and a bigger board cost more; but that much?
