passive 2HP Eurorack gate & trigger utility
current version:
PCB V1.1
Panel V1.1
Features
Trigger Warning allows you to do a couple of things with gate and trigger signals:
-switch between two inputs
-merge two inputs (logical OR)
-mute the output signal
-route the output signal to one of two destination
Manual
Build
The module is trivial to build - only 12 components are soldered.
Allign the jacks and switches with the pcb and panel as best as possible before soldering. Edges of the plastic body of the jacks can protrude from the 2HP contour of the module if you don't.

Questions
How big is the TW PCB 1V1 PCB?
It measures 9.2 × 103.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TW PCB 1V1 use?
13 parts, built around the BAT42. 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 TW PCB 1V1 KiCad files?
From the mzourack/TRIGGER-WARNING repository on GitHub, at the commit this page was made from: the board is TW_PCB_1V1/TW_PCB_1V1.kicad_pcb and its schematic TW_PCB_1V1/TW_PCB_1V1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TW PCB 1V1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mzourack before reusing the design.
