Questions

How big is the MS951 PCB?

It measures 160 × 94 mm and has 2 copper layers, 1.6 mm thick.

What parts does the MS951 use?

246 parts, built around the 1N5357B and IRF540N. 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 MS951 KiCad files?

From the jaylogue/MS951 repository on GitHub, at the commit this page was made from: the board is pcb/MS951.kicad_pcb and its schematic pcb/MS951.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the MS951 design in my own project?

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