Questions
How big is the O12imu PCB?
It measures 12.5 × 12.5 mm and has 2 copper layers, 0.8 mm thick.
What parts does the O12imu use?
16 parts. 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 O12imu KiCad files?
From the qwertpas/O12imu repository on GitHub, at the commit this page was made from: the board is O12imu.kicad_pcb and its schematic O12imu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the O12imu 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).
