Also a key factor may have been the time required to get their own stuff certified vs using off the shelf stuff.

- joezydeco 11y agoA lot of people prototyping in the IoT space are using the precertified modules. There's not much more to it: the transmitter is already soldered to a small piece of PCB but has the antenna and necessary tuned discretes on there and ready to go. Doesn't add much to the cost: like BillinghamJ says it's the certification time and cost that's not really worth the trouble if you can just amortize it into the cost of the module.
- minthd 11y agoThe cost comes from adding another company to the process - the module maker. But sure, at this stage it might not be worth it , maybe later.
- joezydeco 11y agoHardly a concern anymore. These are just line items on a bill of materials now: http://www.digikey.com/product-detail/en/450-0103C/450-0103C-ND/4331947 http://www.digikey.com/product-detail/en/450-0103C/450-0103C...
- minthd 11y ago$7.8 is pretty expensive when you can get a bluetooth mcu(in volume, from dialog i think) for $1.
- joezydeco 11y agoLike we said earlier, you can choose between a raw chip (like the Dialog) and handle the antenna design and all the various governmental certifications and testing yourself ($$$)..or you can buy a precertified module that drops in and you're ready to go. It depends what you can afford and what each path will save you in the long run.
