Questions
How big is the Power supply PCB?
It measures 74 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power supply use?
20 parts, built around the MAX1771ESA+T and IRF644PBF. 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 Hardware7253/OperationUrd repository on GitHub, at the commit this page was made from: the board is cad/PCBs/power_supply/power_supply.kicad_pcb and its schematic cad/PCBs/mechanical_switch_breakout/mechanical_switch_breakout.kicad_sch. 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 MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
