Questions
How big is the Power supply PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power supply use?
38 parts, built around the L7805, L7809 and L7905. 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 Power supply KiCad files?
From the SNURocketTeamHanaro/hanaro-daq repository on GitHub, at the commit this page was made from: the board is KiCAD/power-supply/power-supply.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power supply design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
