Cheap serial WiFi


came across this cheap WiFi module…


Did you find a datasheet for it? That seems like a lot of pins for a serial connection.


Looks like it also support Ethernet – so that’s another 8 pins.


@ ianlee74 - found some more info at


Very interesting !!! We might finally see a cheap WiFi module …
Yay WiFi under $20 who’s up for the challenge ???



@ ianlee74 -

I found this…


Nice. Gotta love the “Ralink Confidential” watermarks all over it. You better download that one before it disappears :wink:

I hope someone tries this out. I’m still sitting on a TI CC3000 that I haven’t had time yet to try and decipher.
