Questions
How big is the MD mini PCB?
It measures 60.6 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MD mini use?
84 parts, built around the IRS2003PBF. 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 MD mini KiCad files?
From the 22060/2025 repository on GitHub, at the commit this page was made from: the board is kicad/MD_mini/MD_mini.kicad_pcb and its schematic kicad/EDzissen/EDzissen.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MD mini design in my own project?
Its repository states no licence, so its author keeps all rights: ask 22060 before reusing the design.
