Hi y'all
I'm working on a personal project that I prototyped using an Arduino uno. Now I'm paying a guy to make a more streamlined version (mine had several issues I didn't know how to solve) and I would like to make the prototype using the microcontroller that will be used on the final design.
My question is what would be a good choice for mass production to replace the Atmega 328? The asumption here is that there might be cheaper options
My product has 2 knobs to set temperature and time, 4 thermistors, and 4 PID loops (one for each heating element).
Please let me know if I'm omitting information that would allow you to give me a proper answer.
Thanks a lot!
PS: Someone suggested SMT32. Any thoughts?

Any cheap microcontroller which has enough GPIO pins, has an on-chip A/D-converter, and which has enough Flash memory+RAM looks suitable for your application as a temperature controller typically doesn't require any fast real-time computations. However, you may also pay attention to the actual development time/cost as each hour spent for development will cost money, so pick a processor that you are familiar with and which has good set of tools (compilers, IDE etc.) available in order the reduce overall development time. For 10 000 units this may still be significant, but for 1000 000 units the actual development cost is less important and the price of the microcontroller is more important.
