Directory
0_PAY_3D_Model_Library, 0_PAY_Footprint_Library.pretty, 0_PAY_Symbol_Library are libraries for all payload PCBs to use. Use the convention ${KIPRJMOD}/../0_PAY_Symbol_Library/(symbol file) so that library paths are referenced relative to the project path rather than absolute to your specific computer's filesystem.
All PIB and related designs to actually be mounted on satellite should be created as projects in the repo base directory. Any test articles should be created in the test-articles folder.
simulation should include any relevant MATLAB simulation or spreadsheeting.

Questions
How big is the PIB PCB?
It measures 80 × 49 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PIB use?
319 parts, built around the 74AHC1G125GW, 74LVC2G17GW, MIC4424YM and LT8580EDD#PBF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PIB KiCad files?
From the apexsat/payload-electrical repository on GitHub, at the commit this page was made from: the board is 200_40 PIB/PIB.kicad_pcb and its schematic 200_40 PIB/DPT Mux.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PIB design in my own project?
Its repository states no licence, so its author keeps all rights: ask apexsat before reusing the design.
