Questions
How big is the IchnaeaV2 PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the IchnaeaV2 use?
444 parts, built around the RP2040, W25Q32JVZPIQ, 74HC4051PW and LM1117MP-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 IchnaeaV2 KiCad files?
From the brandonbraun653/Ichnaea repository on GitHub, at the commit this page was made from: the board is hw/ver2/IchnaeaV2/IchnaeaV2.kicad_pcb and its schematic hw/ver1/PowerStage/IchnaeaV1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IchnaeaV2 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).
