Questions
How big is the Base PCB?
It measures 99.6 × 50.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Base use?
77 parts, built around the 74HC595, DS1307ZN, KW4-361AVA and LM35. 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 Base KiCad files?
From the augustocrmattos/PQDB-Hardware repository on GitHub, at the commit this page was made from: the board is PQDB-Mini-HW-Kicad/Base.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Base design in my own project?
Its repository states no licence, so its author keeps all rights: ask augustocrmattos before reusing the design.
