Schematic Original File

I need a original CAD file of below attached file. Can you send me?
PAB-BASE-RC05-sch.pdf (343.5 KB)

Maybe you can find out in here:

I meant it was design file not pdf file. I need a design file like pads or altium, allegro.

I guess there is no official version Altium file sharing. I’m trying to redraw the altium schematic for pixhawk 6C base on stande and pdf file. But it will take some time.
