Questions
How big is the IMU PCB?
It measures 30 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IMU use?
30 parts, built around the ICM-20948, MIC5365-1.8YC5-TR and BSS84. 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 KiCad files?
From the someonelse20/drone repository on GitHub, at the commit this page was made from: the board is pcb/IMU/IMU.kicad_pcb and its schematic pcb/IMU/IMU-backups/IMU-2025-06-25_161459/IMU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IMU design in my own project?
Its repository states no licence, so its author keeps all rights: ask someonelse20 before reusing the design.
