Questions
How big is the MHCNC PCB?
It measures 195 × 123 mm and has 4 copper layers, 1.61 mm thick.
What parts does the MHCNC use?
417 parts, built around the ISO3086DW, B0305XT-1WR3, TBD62783APG and LDL212DR. 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 MHCNC KiCad files?
From the TheHexaCube/MHCNC repository on GitHub, at the commit this page was made from: the board is MHCNC.kicad_pcb and its schematic MHCNC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MHCNC design in my own project?
Its repository states no licence, so its author keeps all rights: ask TheHexaCube before reusing the design.
