Questions
How big is the Twostep PCB?
It measures 80 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Twostep use?
68 parts, built around the ATXMEGA16E5-AU, LM2674MX-3.3 and B160-13-F(MS). 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 Twostep KiCad files?
From the macpod/twostep_hardware repository on GitHub, at the commit this page was made from: the board is twostep.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Twostep design in my own project?
Its repository states no licence, so its author keeps all rights: ask macpod before reusing the design.
