I am working on a small Arduino project that once successful I think about commercializing (in my case, its a smart tag, but asking in general).

The question is - what is the next step? how do I get a chip that can be more cost effective, and smaller (I don't need all the Arduino abilities for a smart tag)? Is there an online website, service, or do I must approach a professional (and who?)

Thanks in advance,

  • Starting a manufacturing and marketing business, redesigning a product for manufacturing and getting a product safety approved in the US, EU and elsewhere are probably outside the scope of this Q&A website. – RedGrittyBrick May 25 at 10:28
  • What do you mean with "working product"? For me it sound like you have just build up the circuit on a breadboard or perfboard. I wouldn't consider that to be a working product, since "working" in the context of a customer is different from the developer. If you are currently using an Arduino board, you can build another prototype with a standalone microcontroller (and choosing a controller, that is cheap, but also has all the functionalities, that you want). Buy the DIP package of it and build again on the breadboard. – chrisl May 25 at 11:05
  • After that you can learn to use programs like Eage, KiCAD, ... which are used to first create a schematic and from that a PCB layout, that you can get manufactured (and even soldered with components) by one of the many PCB manufacturers. Here you can choose way smaller packages for each component (more SMD instead of through-hole). – chrisl May 25 at 11:07
  • This is very broad as asked and strays quickly into opinion and non-technical areas. I mean... you get a chip by buying one--they're available at essentially any electronics seller (DigiKey, Mouser, direct from the manufacturer, and so on.) As far as designing a board, if it's outside your area of knowledge, I'd start by searching the web. Find someone that can design for product approval, though; depending on the board it can be annoying. You're designing for a very competitive, low-margin, commoditized space. – Dave Newton May 25 at 12:27
