Questions
How big is the 9outputs PCB?
It measures 57.6 × 81.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 9outputs use?
23 parts, built around the BSP75N and KPJX-4S-S. 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 9outputs KiCad files?
From the Hackuarium/Avionics repository on GitHub, at the commit this page was made from: the board is kicad-9outputs/9outputs.kicad_pcb and its schematic kicad-10outputs/10outputs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 9outputs design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hackuarium before reusing the design.
