I’ve been looking for cheap wifi modules for arduino for a while. There is now a ESP8266 that might do what I want for a reasonable price. Seeedstudio sells it and are about to write some documentation for it. I also came across this blog entry that I’m going to follow:
Recently we blogged about the new ultra low cost UART to WIFI modules based on ESP8266 ICs. Today the WIFI modules and sample chips arrived so we can finally test them.
The low cost $5 modules focused the interest of many people. We already have translated datasheet, forum and some people even started write code for Arduino without having these modules at all 🙂
One problem I see is that there are no official schematic with components with values nor reference design. We are going to change this as we already got 3 different modules and the components around ESP8266 are not so many, so we will capture the schematic and make reference PCB layout in the next few days.
