Questions
How big is the AtmegaStepperDriver PCB?
It measures 94.5 × 67.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AtmegaStepperDriver use?
102 parts, built around the ATMEGA328P-PU, BC547, BC557 and TIP41C. 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 AtmegaStepperDriver KiCad files?
From the eGuardianDev/atmegaStepperDriver repository on GitHub, at the commit this page was made from: the board is PCB/atmegaStepperDriver/atmegaStepperDriver.kicad_pcb and its schematic PCB/atmegaStepperDriver/Gate.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AtmegaStepperDriver 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).
