Questions
How big is the Schematic MD PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Schematic MD use?
180 parts, built around the UCC21520DW, 74HC04D, L78M05ABDT-TR and MAX3051EKA. 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 Schematic MD KiCad files?
From the Mochizuki12/schematic_MD repository on GitHub, at the commit this page was made from: the board is schematic_MD.kicad_pcb and its schematic Driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Schematic MD design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
