Questions
How big is the BSPD-27 PCB?
It measures 82.5 × 85.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BSPD-27 use?
108 parts, built around the R-78E5.0-1.0, SN74HC00DR(LX), SN74HC02DR(LX) and LM2901DR. 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 BSPD-27 KiCad files?
From the Full-Blue-Racing/BSPD-27 repository on GitHub, at the commit this page was made from: the board is BSPD-27.kicad_pcb and its schematic BSPD-27.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BSPD-27 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Full-Blue-Racing before reusing the design.
