Questions
What parts does the ProjectScematic PCBv2 use?
39 parts, built around the ATMEGA32A-PU and MAX31820MCR+. 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 ProjectScematic PCBv2 KiCad files?
From the danielopaleye01/SmartHomeSystem repository on GitHub, at the commit this page was made from: the board is Final_Project430 2/Final_Project430 2/ProjectScematic_PCBv2.kicad_pcb and its schematic Final_Project430 2/Final_Project430 2/ProjectScematic_PCBv2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProjectScematic PCBv2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask danielopaleye01 before reusing the design.
