Questions

How big is the Drum trigger adapter PCB?

It measures 58 × 20 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Drum trigger adapter use?

7 parts. 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 Drum trigger adapter KiCad files?

From the adeboni/electronics repository on GitHub, at the commit this page was made from: the board is drum_adapter/pcb/drum_trigger_adapter.kicad_pcb and its schematic alien_screamer/alien_screamer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Drum trigger adapter design in my own project?

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