The 27 most common of 28 parts.
It measures 89.6 × 87.4 mm and has 2 copper layers, 1.6 mm thick.
28 parts, built around the ULN2003A and SC0918. 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 JavierGONL/bd-pi repository on GitHub, at the commit this page was made from: the board is PCB/pcb_bd_pi.kicad_pcb and its schematic PCB/pcb_bd_pi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask JavierGONL before reusing the design.
