Questions

How big is the LOF PCB?

It measures 180 × 97 mm and has 4 copper layers, 1.6 mm thick.

What parts does the LOF use?

68 parts, built around the PEL12D-4225S-S1024, 4816P-T01-103LF, M20-7822046 and PTL60-15O1-104B2. 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 LOF KiCad files?

From the LauriAlanen/ModuMIDI repository on GitHub, at the commit this page was made from: the board is hardware/pcb/Kicad/LOF.kicad_pcb and its schematic hardware/pcb/Kicad/LOF.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the LOF design in my own project?

Its repository states no licence, so its author keeps all rights: ask LauriAlanen before reusing the design.
