Questions
How big is the TGW71 PCB?
It measures 344.5 × 98.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TGW71 use?
300 parts, built around the AT90USB1286-AU and BAV70L. 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 TGW71 KiCad files?
From the Gouty/Prism_Keyboard repository on GitHub, at the commit this page was made from: the board is pcb/TGW71.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TGW71 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gouty before reusing the design.
