Questions
How big is the DrillPowerSupply PCB?
It measures 69 × 55 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DrillPowerSupply use?
15 parts, built around the NE555P. 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 DrillPowerSupply KiCad files?
From the bprager/DrillPowerSupply repository on GitHub, at the commit this page was made from: the board is DrillPowerSupply.kicad_pcb and its schematic DrillPowerSupply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DrillPowerSupply design in my own project?
Its repository states no licence, so its author keeps all rights: ask bprager before reusing the design.
