Questions
How big is the Croaky4 PCB?
It measures 73 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Croaky4 use?
39 parts, built around the ATMEGA32U2-AU, PRTR5V0U2X and WS2812B. 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 Croaky4 KiCad files?
From the Selovert/Croaky4 repository on GitHub, at the commit this page was made from: the board is Croaky4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Croaky4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Selovert before reusing the design.
