Questions
How big is the IMU Array PCB?
It measures 74 × 93 mm and has 4 copper layers, 1.6 mm thick.
What parts does the IMU Array use?
23 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 IMU Array KiCad files?
From the Sphyrna-029/IMU-Array repository on GitHub, at the commit this page was made from: the board is imu-array.kicad_pcb and its schematic imu-array.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IMU Array design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sphyrna-029 before reusing the design.
