Questions
How big is the MicroIMU PCB?
It measures 17.8 × 10.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MicroIMU use?
12 parts, built around the LIS2MDL and BMI323. 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 MicroIMU KiCad files?
From the hlord2000/MicroIMU repository on GitHub, at the commit this page was made from: the board is MicroIMU.kicad_pcb and its schematic MicroIMU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MicroIMU design in my own project?
Its repository publishes it under the CERN-OHL-P-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).
