Questions
How big is the Imu PCB?
It measures 60.8 × 59.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Imu use?
45 parts, built around the ESP32-C3-WROOM-02-H4, LIS2MDL, AMS1117-3.3 and LSM6DSL. 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 kayneyao/localization-io repository on GitHub, at the commit this page was made from: the board is imu.kicad_pcb and its schematic LSM6DSL/LSM6DSL.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 kayneyao before reusing the design.
