README

Hardware/Front Panel/README.md

Front Panel

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!

Questions

How big is the Patch Passive Board PCB?

It measures 19 × 108 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Patch Passive Board use?

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.

Where can I download the Patch Passive Board KiCad files?

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.

Can I use the Patch Passive Board 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).
