To save time, only made 'absolutely necessary corrections'
- Oriented R82 and D71 correctly in schematic
- Added 0.1uF decoupling capacitors for op amps
- Moved decoupling capacitors closer to IC it is supporting
- Moved ports closer to the edge
- Added reverse voltage protection at the power port
- Added stitching vias

Started making BOM
- Sourcing everything from Digi-key
- Started sourcing components on Digi-key, down 15 out of 91
- Made a mistake in the footprint from some of the capacitors, some are non-stocked on Digi-Key and or Mouser, all of the issues were resolved
