Questions
How big is the InerCal PCB?
It measures 35 × 31 mm and has 2 copper layers, 1.6 mm thick.
What parts does the InerCal use?
15 parts, built around the ICM-42688-P and KP-1608CGCK. 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 InerCal KiCad files?
From the ElfDeMaison/InerCal repository on GitHub, at the commit this page was made from: the board is HardWare/InerCal.kicad_pcb and its schematic HardWare/InerCal.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the InerCal design in my own project?
Its repository states no licence, so its author keeps all rights: ask ElfDeMaison before reusing the design.
