Questions
How big is the MCU PCB?
It measures 22.3 × 63 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MCU use?
5 parts. 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 MCU KiCad files?
From the Ethancao123/ECE395 repository on GitHub, at the commit this page was made from: the board is TestBoard/MCU/MCU.kicad_pcb and its schematic FinalBoard/FinalBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MCU design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ethancao123 before reusing the design.
