Questions
How big is the Rotary USB PCB?
It measures 42.5 × 37.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rotary USB use?
30 parts, built around the ATMEGA32U4-AU, SP0503BAHTG and MF-FSMF050X-2. 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 Rotary USB KiCad files?
From the GadgetReboot/Rotary_USB repository on GitHub, at the commit this page was made from: the board is KiCad/Rotary_USB.kicad_pcb and its schematic KiCad/Rotary_USB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rotary USB design in my own project?
Its repository states no licence, so its author keeps all rights: ask GadgetReboot before reusing the design.
