Questions
How big is the ProjectAtlas PCB?
It measures 93.5 × 101 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ProjectAtlas use?
131 parts, built around the STM32G474RET6, TJA1051T/3/1, MPM3610GQV-P and PACDN042Y3R. 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 ProjectAtlas KiCad files?
From the BYU-Racing/SH_PCB repository on GitHub, at the commit this page was made from: the board is ProjectAtlas.kicad_pcb and its schematic ProjectAtlas.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProjectAtlas design in my own project?
Its repository states no licence, so its author keeps all rights: ask BYU-Racing before reusing the design.
