This is a Bixler V1.1 mount for the PIXHAWK/PX4 autopilot and all its accessories, there is room enough for the autopilot, rc radio, GPS, fpv camera etc.
The
...Plus assembly is pretty straight forward, you can help yourself with the pictures.
When assembled it is recommended to superglue everything together, you don't want it disassemble in mid-air.
The holes in the bottom plate are for the PX4, if you want to install the PIXHAWK or any other autopilot you could use double sided tape.
