Questions

How big is the Kit Trig Sampler PCB?

It measures 78 × 109.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Kit Trig Sampler use?

86 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 Kit Trig Sampler KiCad files?

From the 4ms/pcb-Kit-Trig-Sampler repository on GitHub, at the commit this page was made from: the board is protos/p1/Kit-Trig-Sampler.kicad_pcb and its schematic protos/p1/Kit-Trig-Sampler.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Kit Trig Sampler design in my own project?

Its repository states no licence, so its author keeps all rights: ask 4ms before reusing the design.
