Fberbari/AAquad
(OUTDATED, see AAQuad-Evolution) a baremetal implementation of a multirotor flight computer.
It measures 74 × 97.5 mm and has 2 copper layers, 1.6 mm thick.
25 parts, built around the NC7SZ157P6X. 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.
From the SFUSatClub/Antenna_Feed repository on GitHub, at the commit this page was made from: the board is Antenna-Feed.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask SFUSatClub before reusing the design.
