All resolved from very beginning...

Im really trying to help with parts here but Im waiting for very simple parts approval (gps with 4 contacts) for week+ already... FC submission was about the same timing.

Awesome work! I guess you can make it cheaper by creating hd version with no OSD chip. Boot button can be removed too, I have zero cases for years where I need a button on FC. USB can be replaced with cheap jst connector in case you planning to make more versions/units so you need single adapter for all of them...
