Questions
How big is the PWR PCB?
It measures 74 × 72 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PWR use?
20 parts, built around the LM7805. 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 PWR KiCad files?
From the macmade/PWR repository on GitHub, at the commit this page was made from: the board is PWR/PWR.kicad_pcb and its schematic PWR/PWR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PWR design in my own project?
Its repository states no licence, so its author keeps all rights: ask macmade before reusing the design.
