How to choose a single board computer with wi-fi?

Question

WiFi

I have a weather station assembled on arduino + ethernet with connected sensors. I really want to transfer to wi-fi. Due to the fact that the arduino wi-fi shield costs exorbitant money, I began to look for analogues.
There are several requirements: 1) wi-fi, 2) inputs for connecting sensors. The price must be the lowest. Everything else can be excluded in order to reduce the cost of construction.
Tell me which model of a single-board computer is most suitable for these purposes.

Answer 1

The first thing that comes to mind for your idea is to use ElectricIMP habrahabr.ru/post/164105

Answer 2

There are still such modules www.econais.com/products/wismart-modules, however, unlike the previous ones, it did not work with them. But it looks promising. I think it will be easier to implement 1wire on this module
