Questions
How big is the Power PCB?
It measures 48.8 × 19.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power use?
30 parts, built around the MCP1640-I/MC. 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 KiCad files?
From the trozamon/eecs373-project repository on GitHub, at the commit this page was made from: the board is kicad/power.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power design in my own project?
Its repository states no licence, so its author keeps all rights: ask trozamon before reusing the design.
