Questions
How big is the PbMonitor v1.0 PCB?
It measures 53.3 × 35.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PbMonitor v1.0 use?
24 parts, built around the AMS1117-3.3. 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 PbMonitor v1.0 KiCad files?
From the ElektorLabs/Pb-Monitor repository on GitHub, at the commit this page was made from: the board is hardware/PbMonitor-v1.0/PbMonitor-v1.0.kicad_pcb and its schematic hardware/PbMonitor-v1.0/PbMonitor-v1.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PbMonitor v1.0 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).
