Questions
What parts does the Xiao rv01β use?
23 parts, built around the MCP3208-BI/P and MCP23S17-E/SO. 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 rv01β KiCad files?
From the logica0419/tinygo-rover-workshop repository on GitHub, at the commit this page was made from: the board is hardware/pcb/xiao-rv01β/xiao-rv01β.kicad_pcb and its schematic hardware/pcb/xiao-rv01β/xiao-rv01β.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Xiao rv01β 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).
