To create a ground plane in KiCad, follow these steps:

  1. Open your PCB layout in KiCad’s PCB Editor.

  2. Select the appropriate layer for your ground plane. Typically, this is one of the copper layers like F.Cu (front copper) or B.Cu (back copper).

  3. Create a zone:
    • Click on the “Add filled zones” tool (the icon looks like a square with a diagonal line).
    • Choose the net for the ground plane, usually “GND”.
    • Select the layer where you want the ground plane.
  4. Draw the zone:
    • Click to start drawing the outline of your ground plane.
    • Continue clicking to outline the area you want to cover with the ground plane.
    • Right-click and select “Close Outline” or double-click to finish the zone.
  5. Adjust zone settings:
    • Double-click on the zone outline to open the Properties dialog.
    • Adjust the clearance, minimum width, and other parameters as needed.
  6. Fill the zone:
    • Right-click on the PCB and select “Zones” > “Fill All Zones” to create the ground plane.
    • The ground plane will fill the designated area, connecting to all GND pads and vias within the zone.
  7. Verify the ground plane:
    • Ensure that the ground plane connects properly to all intended GND points.
    • Check for any clearance issues with other nets.
  8. Update and save your design.
