Questions
How big is the Power supply PCB?
It measures 103.4 × 73 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power supply use?
104 parts, built around the LM3914, MCP6041-I/P, MIC2185YM and TPD2E001DZD. 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 vt-amplab/basic-soldering-cert-board 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 publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
