I've looked at the schematics and provided layout, and there's no way this data is usable.
There are TONS of errors in schematics, lots of things connected wrong, for example in sensors, i2c buses, touchscreen interface, all the bypass capacitors are missing, the whole thing basically needs thorough checking for EVERY PAGE.
The layout is a joke too, 1206 passives?!
This will need ALL the datasheets to be provided to even begin completing schematic.
This is not a "$250" budget project, more like $10k+
When you paid your previous freelancer $250 to complete it, that's what you got back.
