Questions
How big is the PI CNC PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PI CNC use?
27 parts, built around the ATMEGA2560-16AU, CP2102N-A01-GQFN28R, TPS54360DDA and CAT24C32LI-. 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 PI CNC KiCad files?
From the muccc/PI-CNC repository on GitHub, at the commit this page was made from: the board is Hardware/PI-CNC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PI CNC design in my own project?
Its repository states no licence, so its author keeps all rights: ask muccc before reusing the design.
