Anyone knows where to buy Fez cobra II WiFi option with uFL connector, when I only need 1-3 pices ?
I guess that’s not what he means. He wants this board - http://www.ghielectronics.com/catalog/product/398 - but with the uFL connector instead of internal antenna.
I had the same question and emailed GHI inquiring it, they said that the minimum order is 100 pieces 
If a Cobra II with WiFi and a uFL connector is what is desired, then buy a http://www.ghielectronics.com/catalog/product/399 and a http://www.ghielectronics.com/catalog/product/379. Then with a little soldering, the desired device is born.
How important is it to solder the ground connection in the middle of the WiFi module? There’s a matching area on the cobra ii board without solder mask so it looks like it’s meant to be soldered, but you can’t really access it.
IIRC, we tested it without the middle pad and it worked but this does not guarantee anything.
I have purchased Cobra II without WIFI and RS9110-N-11-22-05 WiFi module and soldered it my self.
But 3 resistors(33, 1K an 4,7K) and 2 capacitor (1uF and 10uF) is also needed to get it working.
But now it works fine.
Thanks for the advice
Glad it worked for you.
