Questions

How big is the DebugVCFSeparate PCB?

It measures 90 × 79 mm and has 2 copper layers, 1.6 mm thick.

What parts does the DebugVCFSeparate use?

54 parts, built around the LM13700M. 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 DebugVCFSeparate KiCad files?

From the wakimizufu/MC2 repository on GitHub, at the commit this page was made from: the board is debugVCFSeparate/debugVCFSeparate.kicad_pcb and its schematic EGSeparate/EGSeparate.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the DebugVCFSeparate design in my own project?

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