Questions
How big is the M65 PCB?
It measures 256 × 128 mm and has 2 copper layers, 1.6 mm thick.
What parts does the M65 use?
247 parts, built around the 74AHC1G125GW, 74HC595, TPS2553DBVR-1 and SK6805E-J. 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 M65 KiCad files?
From the m-lego/m65 repository on GitHub, at the commit this page was made from: the board is m65.kicad_pcb and its schematic m65.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the M65 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).
