Questions
How big is the Trac PCB?
It measures 111.8 × 161.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Trac use?
103 parts, built around the PIC32MX250F128B-I/SS, MAX3232ID, LT1074CT7#PBF and LT1176CN8#PBF. 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 Trac KiCad files?
From the tractiming/trac-pcb repository on GitHub, at the commit this page was made from: the board is trac.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Trac 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).
