Where can I find project details?

Question

Arduino

Where do all startups find the necessary parts for their projects? For example, I need a touch screen, but the proposed modules for Arduino do not suit me. Where can I find or order a component?

Answer 1

You assemble a prototype on what you have, test it, bring it to mind.
When you decide that it is already worthy to enter the market, go to the manufacturer and say "I want", they tell you how much your want costs.
Well, or right now you go to the manufacturer of the same displays and name your wants, the manufacturer will tell you what he can give from what he has, in a batch of 1000 pieces. :)

Answer 2

Personally, I buy Chip and Dip in the store .
If you need to find the name of a component with some specific parameters, then I look in the Farnell catalog . There you can also order to Russia, if the order amount is from 300 dollars.
Finally, there are some very specific components that can only be found on Google. Google. In most cases, googled can be purchased on Ebay .
The most important thing is that a datasheet is available for the component. Then you can somehow use it in your project. It won't work without a datasheet.
Most of the datasheets are on AllDatasheet.com . If it is not there, then it is unlikely to be found on the Web.
Although somehow I found a service manual in Chinese on a Chinese forum. With its help, we managed to figure out what kind of DAC is installed on the board, and even then google the datasheet for it. Another question is that the DAC itself has not been produced for a long time and a new one is no longer available.
