Questions
How big is the Minsis mcs51 PCB?
It measures 50.6 × 68.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Minsis mcs51 use?
24 parts, built around the AT89S51-24PU and LM7805. 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 Minsis mcs51 KiCad files?
From the MuHafidzh/SET repository on GitHub, at the commit this page was made from: the board is Task/minsis_mcs51/minsis_mcs51.kicad_pcb and its schematic Task/minsis_mcs51/minsis_mcs51.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minsis mcs51 design in my own project?
Its repository states no licence, so its author keeps all rights: ask MuHafidzh before reusing the design.
