Right, got the FrSky gear delivered today but when I took the radio to bits I think I maybe have discovered a problem.

Read some reviews etc on it and how to guides and just couldn't find the board they were talking about. So, looked up a video and Jamie's guide on here and saw the that board appears to be attached to the trainer port. Here lies the problem...





Looks almost like the board has been changed in favour of some other sort of trainer connector? Whatever it is, I have been thoroughly confused by it, hopefully someone can enlighten me.
