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. Iā€™m trying to redraw the altium schematic for pixhawk 6C base on stande and pdf file. But it will take some time.
