Testboard for the Eurorack Module for a manual gate/trigger source
As described in #53, buttons do not always trigger reliably after a cold start, i.e. a longer period without power.
This happens on all buttons, but only in the finished circuit. The effect could not be observed on the breadboard and is therefore hard to debug.
This board contains only one trigger and some testpoints.
It is meant to be connected to the Eurorack Power Breakout.

Questions
How big is the Manual gate trigger source PCB?
It measures 108.9 × 110.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Manual gate trigger source use?
115 parts, built around the BC547. 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 Manual gate trigger source KiCad files?
From the moPsy-project/manual-gate-trigger-source repository on GitHub, at the commit this page was made from: the board is PCB/manual-gate-trigger-source.kicad_pcb and its schematic PCB/cv_input.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Manual gate trigger source design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
