Yes, I have experience with CTS labs in Guangzhou. They handle the FCC 15b testing and fcc id for us.

Maybe someone speaks English there.
The label implies the module has an external PA. That will help a lot with range. But it will make passing FCC much harder.esp8266 specs wrote:high power PA capable of delivering +25dBm (peak)
If you look at the drawings there are no additional IC footprints.

From this you can see that there are only 3 large components and 8 small passive ones onboard: The one labeled "33" is the ESP8266, the 8-pin SOIP is of course the SPI Flash chip, and the 4-pin one is the crystal (with only 1 stray cap, grrr...), so no PA here.
