Questions
How big is the Mutteruhr PCB?
It measures 67 × 86 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mutteruhr use?
50 parts, built around the ATMEGA328-PU and L298HN. 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 Mutteruhr KiCad files?
From the Race666/masterclock repository on GitHub, at the commit this page was made from: the board is Hardware/Mutteruhr V3/Mutteruhr/Mutteruhr/Mutteruhr.kicad_pcb and its schematic Hardware/Mutteruhr V3/Mutteruhr/Mutteruhr/Mutteruhr.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mutteruhr design in my own project?
Its repository states no licence, so its author keeps all rights: ask Race666 before reusing the design.
