Questions
How big is the IMU PCB?
It measures 85 × 59.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IMU use?
37 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 KiCad files?
From the ni-dotcom/IMULogger_PCB repository on GitHub, at the commit this page was made from: the board is hardware/IMU.kicad_pcb and its schematic hardware/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 ni-dotcom before reusing the design.
