Questions
How big is the SCMplus PCB?
It measures 58.7 × 110.9 mm and has 2 copper layers, 1.11 mm thick.
What parts does the SCMplus use?
144 parts, built around the TL082, CD40109BPWRE4, NCP51460SN33 and BAT54S. 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 SCMplus KiCad files?
From the 4ms/pcb-SCMv3 repository on GitHub, at the commit this page was made from: the board is p4/SCMplus.kicad_pcb and its schematic imported/SCMBO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SCMplus design in my own project?
Its repository states no licence, so its author keeps all rights: ask 4ms before reusing the design.
