Questions
How big is the Senior Design PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Senior Design use?
165 parts, built around the ATMEGA328PB-AU, HX711, LP2985-33DBV and WS2812B. 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 Senior Design KiCad files?
From the bin2ai/Senior_Design repository on GitHub, at the commit this page was made from: the board is Senior_Design.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Senior Design design in my own project?
Its repository states no licence, so its author keeps all rights: ask bin2ai before reusing the design.
