My Older, rebranded 3DR PX4 unit has some data on the SD card, and am trying to find out if it is needed or deletable. Ive attached some photos, of the unit, the Data in the SD card, and would be appreciative of any info on the contents/and /or their value. Im using it for a new project, and cleaning house lol haha, Thanks *Newbie
