Questions
How big is the Trailmaker PCB?
It measures 104 × 35.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Trailmaker use?
15 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 Trailmaker KiCad files?
From the Rubey4112/reactor repository on GitHub, at the commit this page was made from: the board is reactor_pcb/trailmaker.kicad_pcb and its schematic reactor_pcb/trailmaker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Trailmaker 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).
