Questions
How big is the StepperClock PCB?
It measures 119.4 × 64.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the StepperClock use?
27 parts. 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 StepperClock KiCad files?
From the tlsystems/StepperClock repository on GitHub, at the commit this page was made from: the board is StepperClock.kicad_pcb and its schematic StepperClock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StepperClock design in my own project?
Its repository states no licence, so its author keeps all rights: ask tlsystems before reusing the design.
