Questions
How big is the Pilkki PCB?
It measures 32 × 20 mm and has 2 copper layers, 1.09 mm thick.
What parts does the Pilkki use?
62 parts, built around the MIC23050-SYML-TR, 74LVC2T45RA3, TPD2EUSB30ADRT and 0ZCK0100FF2E. 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 Pilkki KiCad files?
From the SmallSharky/Pilkki repository on GitHub, at the commit this page was made from: the board is electronics/pilkki.kicad_pcb and its schematic electronics/pilkki.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pilkki 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).
