Questions
How big is the PwrModule PCB?
It measures 25.9 × 62.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PwrModule use?
31 parts, built around the ATTINY424-SSU. 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 PwrModule KiCad files?
From the CIDCO-dev/Poseidon repository on GitHub, at the commit this page was made from: the board is docs/PCB Design/HB-PM/PwrModule.kicad_pcb and its schematic docs/PCB Design/HB-BP/PwrBypass.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PwrModule 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).
