Patch Passive Board is an open-source printed circuit board by m0xpd, from the m0xpd/PATCH repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 19 × 108 mm with 40 parts on 25 nets, routed with 107 tracks and 0 vias.
Its parts include 30 resistors and 8 connectors.
This folder contains design files for a front panel for the PATCH system, expressed as a KiCad project.
Remember that the schematic is 'empty' - the front panel has no electrical connections.
The front panel has no labels/annotation, because each instance of the system will be put to different use; you can add labels convenient to your own application if you need to.
I find it convenient at least to use different nuts (i.e. knurled or hex) on the sockets to remind me which are inputs and which are outputs, from which I can remember the configuration of the PATCH module. If you are less stingy than me, you could even use coloured nuts!

It measures 19 × 108 mm and has 2 copper layers, 1.6 mm thick.
40 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.
From the m0xpd/PATCH repository on GitHub, at the commit this page was made from: the board is Hardware/Passive Board/Patch Passive Board.kicad_pcb and its schematic Hardware/Buffered Multiple Board/Patch Buffered Multiple Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
