Questions
What parts does the 8051 Microcontroller use?
41 parts, built around the C8051F384-GQ. 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 8051 Microcontroller KiCad files?
From the Deepakkumar128/8051-microcontroller-system repository on GitHub, at the commit this page was made from: the board is 8051 Microcontroller.kicad_pcb and its schematic 8051 Microcontroller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 8051 Microcontroller design in my own project?
Its repository states no licence, so its author keeps all rights: ask Deepakkumar128 before reusing the design.
