The master schematic is within "Senior design mainboard32826 backup"
The master schematic is within "Senior design mainboard32826 backup"
This was the version that everything was verified in as of 4/10/2026
Then for the sake of layout, and neatness broken out into their own project files for each discrete board. This includes swapping and non-swapping
Mainbourd layout pre-weeks check 1 has most up to date version of mainboard PCB this will eventually be made neater again as development continues but this is noted to avoid mistakes for now
