You will need 2 PCBs for this project. The Gerber zip is a zip of 2 gerber (zip) files--front panel and main circuit board. Suggestion: for front panel use a black PCB with white silks. I have also included a BOM and PDF of boards and the schematic. Note that the BOM for Euro version is slightly different vs. the blog posts, which is Frac format.
