Questions
How big is the IMU V100 PCB?
It measures 70 × 70 mm and has 4 copper layers, 1.6 mm thick.
What parts does the IMU V100 use?
40 parts, built around the LC76GABMD, THVD1450DRBR, BMP280 and MIC23050-SYML-TR. 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 IMU V100 KiCad files?
From the embeddedalpha/IMU_V100 repository on GitHub, at the commit this page was made from: the board is PCB/IMU_V100.kicad_pcb and its schematic PCB/Barometer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IMU V100 design in my own project?
Its repository states no licence, so its author keeps all rights: ask embeddedalpha before reusing the design.
