Questions
How big is the Axis PCB?
It measures 70 × 17.5 mm and has 4 copper layers, 1.62 mm thick.
What parts does the Axis use?
43 parts, built around the BMM150, BHI160B, TPS78433QWDRBRQ1 and WS2812. 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 Axis KiCad files?
From the versioduo/axis repository on GitHub, at the commit this page was made from: the board is hardware/axis.kicad_pcb and its schematic hardware/axis.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Axis design in my own project?
Its repository states no licence, so its author keeps all rights: ask versioduo before reusing the design.
