Questions
How big is the Cnc grbl PCB?
It measures 99.8 × 70.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cnc grbl use?
68 parts, built around the ATMEGA328P-AU, FT231XS-R, UA78M05IKC and STB60NF06LT4. 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 Cnc grbl KiCad files?
From the emavap/Grbl-Pro-V2-PCB repository on GitHub, at the commit this page was made from: the board is cnc-grbl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cnc grbl design in my own project?
Its repository states no licence, so its author keeps all rights: ask emavap before reusing the design.
