Questions
What parts does the Speed limit use?
10 parts, built around the ATTINY13-20PU and MCP41010-E/P. 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 Speed limit KiCad files?
From the sinf/cemoto repository on GitHub, at the commit this page was made from: the board is speed-limit-pcb/speed-limit.kicad_pcb and its schematic odometer-pcb/odometer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Speed limit 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).
