After quite a long wait, I think I might install the geolink on my devil 505 goblin clone.
One question though.. what are the markings on the module? 12'o'clock and 3'o'clock.
Ocd
These "marks" are used for antenna impedance matching. They mean nothing for user and each antenna could have different marks or even no marks.
This is made by manufacturer of the part.
