Questions
How big is the GO button PCB?
It measures 52 × 74 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GO button use?
38 parts, built around the ATMEGA32U4-AU, WS2812, GT-USB-7010ASV and JK-NSMD050SF. 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 GO button KiCad files?
From the gztproject/GO-button repository on GitHub, at the commit this page was made from: the board is PCB/GO-button/GO-button.kicad_pcb and its schematic PCB/GO-button/CherrySwitches.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GO button design in my own project?
Its repository states no licence, so its author keeps all rights: ask gztproject before reusing the design.
