- C1, C2, C5, C6 are 0603 metric (0201 imperial), not 0603 imperial
- MicroSD should be at the edge of the board with the opening of the slot facing out - currently the MicroSD cannot be inserted
- Component placement of R1, R2, C3, C4 can be more organized to reduce vias and trace lengths
- Vias and trace lengths should be reduced in general
- 3V3 can be implemented using a polygon instead of daisy chained traces
- Try not to route traces in between pads if it is avoidable
For everyone:
Ground plane pullback!Pull back ground plane from the edges!!!
