Questions
How big is the Powerlog PCB?
It measures 44.3 × 48.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Powerlog use?
40 parts, built around the ATSAMD21E15B-MU and AP2112K-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 Powerlog KiCad files?
From the Matir/hacks repository on GitHub, at the commit this page was made from: the board is pcbs/powerlog/powerlog.kicad_pcb and its schematic electronics/wiretest/wiretest/wiretest.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Powerlog design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
