PCB and Panel files for a Eurorack switch expander. Designed for the 4MS Rotating Clock Divider (RCD), however it should be useable with any Eurorack module where a SPDT switch can replace a three-pin jumper.
PCB is designed using KiCad.
The panel was produced via Front Panel Express (https://www.frontpanelexpress.com/). The included Front Design file (FPD) can be used to order the same panel. The panel text was created in Affinity Designer, and imported into Front Design as a graphic object. To change the text, you can either:
A. Replace the graphic object with text engravings:
- Delete the graphic layer in Front Design.
- Insert Front Design text engravings.
B. Update the graphic object:
- Open the included .AI file in a program that can edit Adobe Illustrator files.
- Edit the text.
- Hide all non-text layers (they are only there as a reference)
- Export to PDF
- Replace the PDF in the 'File' field of the graphic object with your updated object.
