Questions
How big is the Trigger PCB?
It measures 47 × 38.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Trigger use?
20 parts, built around the AQV210E 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 Trigger KiCad files?
From the sethrobles/impact_trigger repository on GitHub, at the commit this page was made from: the board is trigger.kicad_pcb and its schematic trigger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Trigger design in my own project?
Its repository states no licence, so its author keeps all rights: ask sethrobles before reusing the design.
