True. But if you are a hobbyist, at the cusp of commercialization, then the MCU cost is a huge factor in total product cost.
As an example, I made a flow measurement and alarm system for my home. I used an ESP8266 development board, which is damn cheap, at about 5 USD. I successfully completed the project.
However, I decided to explore options for commercialization, and that 5 USD became a huge cost increase for my overall system. So I am now trying to designin systems with MCUs that are less than 30 cents.
- abiogenesis 6y agoIt is true that ESP8266 chips are slightly more expensive than 30 cents, but I believe you were not planning to use the development board for mass production.
- kumarvvr 6y agoYou missed my point. For a commercial product, even 1 USD MCU can be a significant cost addition.
- abiogenesis 6y agoMy comment was a reaction to the following statement. It is true that you should absolutely use the cheapest MCU ignoring the development cost if you are targeting to manufacture millions of those: > and that 5 USD became a huge cost increase for my overall system.
