Questions
How big is the TrueStrike56 PCB?
It measures 278.9 × 138.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TrueStrike56 use?
211 parts, built around the 74AHCT125D, SLSS49E-3, 74HC4051 and SK6812MINI-E. 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 TrueStrike56 KiCad files?
From the byungyoonc/TrueStrike56 repository on GitHub, at the commit this page was made from: the board is hw/rev1/pcb/TrueStrike56.kicad_pcb and its schematic hw/rev1/bottom-plate/bottom-plate.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TrueStrike56 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).
