Questions
How big is the Grbl controller PCB?
It measures 54.6 × 80.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Grbl controller use?
44 parts, built around the EL817 and BZT52C6V8. 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 Grbl controller KiCad files?
From the mp035/grbl_controller repository on GitHub, at the commit this page was made from: the board is pcb/V0/grbl_controller.kicad_pcb and its schematic pcb/V0/grbl_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Grbl controller design in my own project?
Its repository publishes it under the MPL-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).
