Questions
How big is the Inflatables PCB?
It measures 150 × 150 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Inflatables use?
45 parts, built around the TMC2209SILENTSTEPSTICK, WS2812B, AO3400A and SS34. 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 Inflatables KiCad files?
From the gohai/puffer repository on GitHub, at the commit this page was made from: the board is pcb/inflatables.kicad_pcb and its schematic pcb/inflatables.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Inflatables design in my own project?
Its repository states no licence, so its author keeps all rights: ask gohai before reusing the design.
