Questions
How big is the Rcs PCB?
It measures 66 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rcs use?
28 parts, built around the BS170. 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 Rcs KiCad files?
From the Graicc/2D-Spacecraft repository on GitHub, at the commit this page was made from: the board is hardware/pcb/rcs/rcs.kicad_pcb and its schematic hardware/pcb/rcs/rcs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rcs design in my own project?
Its repository states no licence, so its author keeps all rights: ask Graicc before reusing the design.
