Electronic – arduino – Which could be the best solution for Wifi Card for a project

arduinopicwifi

I'm new so sorry if my title isn't the best. I wanted to know (as I google it and didn't find a satisfactory answer) where can I find a Wifi Card connection for a project.

I have a little device I have been designing, and now I want it to communicate via wifi, since I did it with PIC and Arduino, I already find a MicroElectronika and Arduino WIDI Shield, but both are too expensive for my project so I wanted to know if someone had used another option for it, I'm just asking for the link and if it has documentation.

Thanks in advance

Perhaps you also have considered the WiFly Shield https://www.sparkfun.com/products/9954 for USD 70.

Yes, that is expensive compared to, say, an RF Link Transmitter https://www.sparkfun.com/products/10534 for USD 4.

What you get with the first module is all the WiFi on-air protocols, and TCP/IP. Awesome complexity and high power draw.

With the second module you don't get WiFi protocols, you have to use your own, and you have to buy a receiver module as well. But the cost is great. With a much lower power draw.

You might like to consider it as an alternative; wireless, but not WiFi.

(Disclaimer: a research institution owned by my government owns some of the patents in the WiFi portfolio, so I'm a beneficiary at a distance of the additional cost of the first module.)
