Questions
How big is the Power module PCB?
It measures 74.9 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power module use?
20 parts, built around the NE555P and L7805. 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 module KiCad files?
From the emm312/pcb-cpu repository on GitHub, at the commit this page was made from: the board is power-module/power-module.kicad_pcb and its schematic bus/bus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power module design in my own project?
Its repository states no licence, so its author keeps all rights: ask emm312 before reusing the design.
