I’m going to be doing a product run (an LED toy), and our prototypes have been using Pro Minis. At $18 per, it would be great to save some cash. We really only need 3 outputs (all with PWM), maybe 1 input. Can’t be any bigger than a Mini.
Any guesses on the cheapest solution? Is there a particular chip that would be better suited to our pin needs?
Or is it not really cost effective for a small company to do all that extra work (e.g. just stick with the Mini)?
I know my questions are a bit vague, but I’m interested in discussing any of the tradeoffs between arduino vs custom circuits for product runs.
Thanks for your suggestions!
