Questions
How big is the Micro XTCF PCB?
It measures 81.3 × 37.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Micro XTCF use?
23 parts, built around the 74HCT04D. 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 Micro XTCF KiCad files?
From the spark2k06/Micro-XTCF repository on GitHub, at the commit this page was made from: the board is Micro-XTCF.kicad_pcb and its schematic Micro-XTCF.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Micro XTCF 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).
