From the project

PCB and Panel files for a Eurorack switch expander. Designed for the 4MS Rotating Clock Divider (RCD).

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:

1. Delete the graphic layer in Front Design. 2. Insert Front Design text engravings.
