Questions
How big is the TinyStep PCB?
It measures 26 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TinyStep use?
23 parts, built around the ATTINY204-SSN and AP63205WU. 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 TinyStep KiCad files?
From the sebastiangrus/TinyStep repository on GitHub, at the commit this page was made from: the board is TinyStep/TinyStep.kicad_pcb and its schematic TinyStep/TinyStep.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TinyStep design in my own project?
Its repository states no licence, so its author keeps all rights: ask sebastiangrus before reusing the design.
