Questions

How big is the STImu PCB?

It measures 27.5 × 14.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the STImu use?

13 parts, built around the LSM6DSM. 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 STImu KiCad files?

From the nlbutts/STImu repository on GitHub, at the commit this page was made from: the board is electronics/STImu.kicad_pcb and its schematic electronics/STImu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the STImu 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).
