Questions
How big is the Power Supply PCB?
It measures 97.8 × 82.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power Supply use?
43 parts, built around the LM324, LT3080EDD and PN2222A. 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 hxtk/Power-Supply repository on GitHub, at the commit this page was made from: the board is 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 states no licence, so its author keeps all rights: ask hxtk before reusing the design.
