Set board outline to 70mm x 50mm. Apply 0.4mm signal traces and 0.8mm power traces. Add GND copper pour except antenna corner.

flux

I can take care of these PCB layout updates for you in one change set:
  • Set the PCB size (board outline) to 70 mm x 50 mm
  • Apply routing width rules: 0.4 mm for signal nets and 0.8 mm for power nets
  • Update the GND copper pour to exclude an antenna-corner keepout area
Run the proposed change set and tell me which corner you want reserved for the antenna keepout (top-right, top-left, bottom-right, bottom-left), if you have a preference.
