Questions
How big is the XIAO PCB?
It measures 59.1 × 92.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the XIAO use?
26 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 XIAO KiCad files?
From the feintpetal/LeafPad repository on GitHub, at the commit this page was made from: the board is PCB/XIAO.kicad_pcb and its schematic PCB/XIAO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the XIAO design in my own project?
Its repository states no licence, so its author keeps all rights: ask feintpetal before reusing the design.
