Open-source boards designed in KiCad by Schenktronics on GitHub, from 4 repositories. A board’s address here is its repository’s there.
Schenktronics/ST01-multiple
A 3HP Eurorack passive multiple from Schenktronics: two banks of four jacks, and a latching button that links them into one eight-jack multiple. The button doubles as a performance mute. No power needed.
Schenktronics/ST02-levels
A 3HP Eurorack dual passive attenuator from Schenktronics. Each channel has an input, an output, and a level knob, and the second input is normalled to the first, so one signal can go out at two different levels.
