Questions
How big is the Axis2 PCB?
It measures 111 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Axis2 use?
16 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 Axis2 KiCad files?
From the MyFreertosLab/sdrone_quad repository on GitHub, at the commit this page was made from: the board is schema/axis2/axis2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Axis2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask MyFreertosLab before reusing the design.
