Add BN-880 module

[wafflejock]

Have had moderate success with these BN-880 modules for GPS/compass added to some betaflight quads. All they can do with it is point home, tell distance, get speed, and if failsafe will attempt to return towards take off point after ascending, but I still need to test out all the failsafe setup.

Looks good. Some builders add a gps to all their builds, my attempts haven't panned out yet but I'm thinking of trying one of these.

Thanks. Yup I have put one of these on my hexacopter build since hope for that is to eventually get it setup to do long range stuff with iNav, but I figure nice to have some sort of location info and potential return to home option on my 5" ones too so can use them to do some more exploratory flying sometime without worrying too much about losing them in a bush or some body of water .
