Questions
How big is the FabX base PCB?
It measures 62 × 61.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FabX base use?
52 parts, built around the MCP23008-E/P and BCX19. 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 FabX base KiCad files?
From the fabXlabs/fabX_basePCB repository on GitHub, at the commit this page was made from: the board is KiCad_Project/fabX_base.kicad_pcb and its schematic KiCad_Project/fabX_base.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FabX base design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
