I have a question, I’ve got my arduino up and running using sensors and actuators and i’ve got the function I want. Thing is, I’m designing it for a very small object. Is there any way for me to know what size a finished pcb might be that can offer the same function? I’m designing a casing and it’s tough to know what sort of size i’m looking at. I’ve been dissecting watches and other small things so i know that some electronics are really tiny… I’m just really not sure about what my next step would be from arduino to mass production.
If anyone has any idea that’d be really useful!
