From prototyp to product

This is premisses for the production:

  • The PCB for the finale product do not need to be smaller than the arduino.
  • I am using two of the pins but I guess it is a good thing, if the product need to be developed or extended in the future, to have more available pins.
  • I want to be able to reprogram or update the software in the microcontroller later.
  • The production will not be bigger than 5-20 units (maybe less).

The questions are:

  • Should I keep the arduino as the PCB in my product? What is the pros and cons?
  • If I am not using the arduino, what is the best setup to be able to reprogram or update the software?

You can just use an AT tiny chip in your project. You don't need the entire arduino. Just leave header pins to MISO/MOSI/SCK/RESET.

Here's a great write up and I'm sure there are numerous youtube videos to assist you. http://highlowtech.org/?p=1695

Thank you for the link! Will look in to it!

But will it be worth the cost and work just to remove the unnecessary components?

It really depends on your aspirations for your project.

If you're looking to give these away or sell them locally to fiends and acquaintances then there's no problem leaving the arduino onboard, as part of the project.

If you're hoping to market these as a saleable product, then you'll find the cost of the arduino will make your project less competitive in the marketplace. Also having a circuit that consilidates all of your required circuitry onto one board, will present as a more professional product.
