1README
logos-templates-tools/PC104Layout/README.mdTemplate for PC104 to use for the boards. Keep in mind that the four holes on the board are througholes and it is important that all of the boards have the same distance for their throughole parts.
We should also adhere to having 2.54mm headers that are spaced at a certain (non-disclosed) distance from any holes

Questions
How big is the RealQuadcellAmp PCB?
It measures 75.6 × 76.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RealQuadcellAmp use?
61 parts, built around the LM2904. 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 RealQuadcellAmp KiCad files?
From the UChicago-Space-Program/pulse-hardware repository on GitHub, at the commit this page was made from: the board is flight-subsystem-designs/payload/RealQuadcellAmp/RealQuadcellAmp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RealQuadcellAmp design in my own project?
Its repository states no licence, so its author keeps all rights: ask UChicago-Space-Program before reusing the design.
