Questions
How big is the Rapidtrigger keyboard PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rapidtrigger keyboard use?
95 parts, built around the AH49FNTR-G1, CD74HC4067SM96, LM1117GS-3.3 and BSS138. 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 Rapidtrigger keyboard KiCad files?
From the Cacaomeme/g431rapidtrigger repository on GitHub, at the commit this page was made from: the board is rapidtrigger_keyboard/rapidtrigger_keyboard.kicad_pcb and its schematic rapidtrigger_keyboard/rapidtrigger_keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rapidtrigger keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Cacaomeme before reusing the design.
