Questions
How big is the Graduation Project PCB?
It measures 40.1 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Graduation Project use?
27 parts, built around the 24LC1025-I/P and DS1337S+T&R. 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 Graduation Project KiCad files?
From the OmarAtef2003/DataLogger-Board repository on GitHub, at the commit this page was made from: the board is Graduation Project.kicad_pcb and its schematic Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Graduation Project design in my own project?
Its repository states no licence, so its author keeps all rights: ask OmarAtef2003 before reusing the design.
