My plan here is to use the $9 Arduino Nano and the Roving Networks RN-171 serial wifi to make a wifi enabled sensor that can post to the cloud. First step i had to do was solder some legs on the smd wifi chip. These pads are small but you can see in the pictures that i have 4 legs now: tx, rx, gnd and 3.3v.
I put this new setup on a breadboard so that i could reconfigure the pins as needed. I like this sort of “dead-bug” construction.
Next up I have to communicate over serial with the part and has a lot of questions about the best way to do it. For now I am toing to use my FTDI Basic USB from sparkfun.com and teraterm at 9600 (from the user guide). Ill let you know how it goes.
