It will also via the wonders of WiFi have the advantage of turning my ancient WiFi only iPad mini into my nav and traffic radar screen!
I never even dreamed that stuff like this would be possible 5 years ago let alone when I started multiple decades ago!
I know, the children of unregulated aircraft tend to give a sh#it on legal issues and there might be one.
AFAIK connecting a non-certified GPS source to do ADS-B out on transponder ES is still illegal.
