Questions
How big is the Step linear PCB?
It measures 81.3 × 62.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Step linear use?
86 parts, built around the L293D, LM2904, TL082 and 74HC00D. 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 Step linear KiCad files?
From the dzavalishin/hardware repository on GitHub, at the commit this page was made from: the board is _Unused/step_linear/step_linear.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Step linear design in my own project?
Its repository states no licence, so its author keeps all rights: ask dzavalishin before reusing the design.
