Questions
How big is the 11x3 PCB?
It measures 66 × 260.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the 11x3 use?
171 parts, built around the SN74LV1T34DBV, AH49E, SK6812 and 74HCT154D. 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 11x3 KiCad files?
From the miliar/saiboard repository on GitHub, at the commit this page was made from: the board is electronics/kicad_files/11x3/11x3.kicad_pcb and its schematic electronics/kicad_files/11x3/11x3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 11x3 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
