Questions
How big is the GeigerPower PCB?
It measures 67 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GeigerPower use?
43 parts, built around the BZV55C75, RS1K, BAS321 and BC817. 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 GeigerPower KiCad files?
From the MagnusKos/GeigerPower repository on GitHub, at the commit this page was made from: the board is GeigerPower.kicad_pcb and its schematic GeigerPower.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GeigerPower design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
