PCB PCB design files are available on the Mercurial repository for the project here: Hardware repository. Schematic design and PCB layout were done in Eagle. Our board is small enough that the free version of Eagle is adequate for editing. text/html 2023-03-23T02:48:23+00:00 Anonymous (anonymous@undisclosed.example.com) http://protofusion.org/wiki/opentrack:ground_station_application?rev=1679539703&do=diff Ground Station Application The ground station application has been designed to be a simple and user friendly means of tracking the location of the balloon system both in flight and post-landing. System Setup To run the Ground Application you must install a few tools to allow it to function correctly. Failure to intall these tools may result in limited functionality or failure of the application.
