Questions
How big is the StepDown PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the StepDown use?
15 parts, built around the LM2596S-5.0 and 1N6857UR-1. 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 StepDown KiCad files?
From the AlejandroKT/KiCad-Projects repository on GitHub, at the commit this page was made from: the board is StepDown/StepDown.kicad_pcb and its schematic Servo Tester IC 555/Servo Tester/Servo Tester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StepDown design in my own project?
Its repository states no licence, so its author keeps all rights: ask AlejandroKT before reusing the design.
