This is a general repository for any and all eurorack modules that i have designed. I also put DIY stuff here that I made PCB's from some other designers schematic. For example the MFOS PCB.

Questions
How big is the Fjöl PCB?
It measures 278.9 × 128.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fjöl use?
149 parts, built around the TL072, PCM5100PW, REG1117 and BLM21PG221SN1D. 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 Fjöl KiCad files?
From the modulamodula/Eurorack-Modules repository on GitHub, at the commit this page was made from: the board is Fjöl/Hardware/fjöl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fjöl design in my own project?
Its repository states no licence, so its author keeps all rights: ask modulamodula before reusing the design.
