Questions

How big is the FullsizeRapidtrigger PCB?

It measures 425 × 122 mm and has 2 copper layers, 1.6 mm thick.

What parts does the FullsizeRapidtrigger use?

493 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 FullsizeRapidtrigger KiCad files?

From the Cacaomeme/fullsize_rappidtriggerborard repository on GitHub, at the commit this page was made from: the board is fullsizeRapidtrigger.kicad_pcb and its schematic LED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the FullsizeRapidtrigger design in my own project?

Its repository states no licence, so its author keeps all rights: ask Cacaomeme before reusing the design.
