Pcbnew window:
Drag the cursor towards right, horizontally
|
Drag the cursor with the pencil icon horizontally towards the right.
|
Pcbnew window:
Move the cursor vertically towards the bottom-left vertex of the board >> Click once on the editor after crossing the bottom-left vertex. |
Let us move this cursor vertically, towards the bottom-right vertex of the board.
Click once slightly below bottom-right vertex. |
Pcbnew window:
|
Similarly, we will draw a rectangular ground plane outline around board outline.
|
Pcbnew window:
Hover cursor over ground plane outline >>Hover cursor over ground plane outline and board outline. |
I have completed the ground plane outline.
|
Pcbnew window :
Right-click inside the board outline>>
|
Right-click inside the board outline.
|
Press Esc key | Press Esc key to exit the Add filled zones tool. |
Let us now perform Design Rule Check i.e DRC, for the layout we created.
| |
Pcbnew window:
Click on Perform design rules check |
Click on Perform Design Rules check present at the top of the Pcbnew toolbar. |
DRC Control window:
Click on Start DRC
|
Click on Start DRC.
In my case, there are no errors. |
DRC Control window:
Click OK |
Click OK button at the bottom right corner to exit the DRC Control window. |
Now let us see how to add text on our board. | |
Pcbnew window:
Click on F.Silks from the right toolbar.
|
Let us click on F.Silks layer to place text on the Front Silk Layer.
|
Text Properties window:
Type 7805VoltageRegulator in the Text window.
|
I will type 7805VoltageRegulator in the Text window.
|
Pcbnew window:
|
The typed text will be tied to the cursor.
|
Please make sure to click inside the board outline.
| |
Pcbnew window:
Click on Margin layer from the right toolbar
|
Click on Margin layer.
|
Pcbnew window:
Click once the top-right vertex of the board layout.
|
Click once on either vertex of the board layout.
I have chosen the top-right vertex.
|
Pcbnew window:
Hover cursor over horizontal dimension |
We will perform similar steps for placing horizontal dimensions of the layout. |
Pcbnew window:
Press Ctrl and S key together |
Let us press Ctrl and S keys together to save the work.
|
Pcbnew window:
Click on Plot(HPGL, PostScript or Gerber format) icon |
Click on Plot button at the top of the Pcbnew toolbar. |
Plot window:
