Questions
How big is the NLog 9DoF PCB?
It measures 45 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NLog 9DoF use?
55 parts, built around the ATMEGA644PA-AU, MPU-9250, PCA9306D and RX8900CE-NF. 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 NLog 9DoF KiCad files?
From the kentN/nLog_9DoF repository on GitHub, at the commit this page was made from: the board is Hardware/nLog_9DoF/nLog_9DoF-.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the NLog 9DoF design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
