Question

Electronics

Hello, friends!
Tell me where you can buy details of microcircuits, boards, cameras that are installed in phones, gsm modules, gps, wi-fi modules and the like? We are working on the idea of ​​creating a video device, photo fixation with a wireless Internet connection function (similar to ip cameras). Purchase from the factory, or organizations specializing in the sale. Any information would be helpful. Thanks a lot in advance! =)

Answer 1

The most primitive option is to enter in the search engine what you need with the prefix "price". You choose the store that is closer to home with reasonable prices.
It is possible on aliexpress, but it’s not a fact that it will come out cheaper, wait a long time and maybe they won’t send anything at all. Don't forget to film the unboxing.
Aerobatics ask for samples from manufacturers, but for this you need to have a more or less original idea and know at least English. You write a letter, describe the idea, write that samples are needed for the prototype, and if everything works out, you will buy a large batch. Samples are usually free
PS Maybe you should look towards Arduino for prototyping

Answer 2

Is there a radio store in your city? It makes sense to look there.

Answer 3

Before ordering parts for building a prototype anywhere, it makes sense to find a ready-made assembly. Everything that I tried to prototype, as a rule, lies with the Chinese in assembled form, sometimes ready for use or almost ready. The prices are outrageously ridiculous, all the desire to collect on their own disappears.
On the same eBay, there is a lot of smdish stuff, you just need to properly organize the search, taking into account the terminology and scope.
