@tinhead:
Heh, looks like you got a perfect 50 ohms line from the board to the RF connector going there
(Just kidding, of course)

Under 1/7 the wavelength of 2.4Ghz and you should be OK...
Now thats what I am told, anyone know this for a fact (actually I was told 1/10, then I read from what sounded correct 1/7)
Roughly 18mm at 1/7 or 13mm at 1/10

and that's 3mm, not connected to vias (point to point only, module to sma). More problematic is the shitty module design, the GND is complettly shitty routed and on wrong end (not near antenna out) of module. What i additionally did was to remove some solder mask right under th chip and connect to SMA gnd and central gnd point of the extra pcb.

Do you mean the 3.3V that site to either side of the LNA pin? Very odd. I expected GND
