Raspberry Pi publishes only a 'reduced' schematic (known to be missing some nets/reference designators) and a mechanical drawing; no full production schematic or PCB source is released.
'Reduced schematics' is Raspberry Pi's own label for this document; forum reports say it's missing connections/reference designators vs. the shipping board. No KiCad/Eagle/Altium source or Gerbers published. RP3A0 has no separate public datasheet from Raspberry Pi or Broadcom.

What still needs checking
The published schematic is a reduced board reference; do not treat it as a complete RP3A0 internal design.
Confirm camera cable, headers, storage and adapters for the chosen enclosure. 512 MB RAM is a workload constraint, not an application compatibility guarantee.
