Questions
How big is the Airmouse PCB?
It measures 18.5 × 36.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Airmouse use?
25 parts, built around the ICM-20948. 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 Airmouse KiCad files?
From the lymzzyh/Airmouse repository on GitHub, at the commit this page was made from: the board is hardware/airmouse.kicad_pcb and its schematic hardware/airmouse.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Airmouse design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
