KiCad FOSDEM 2018: Status & New Features in KiCad 5


  • Open Hardware Initiative (OHI)
  • CERN Beams department
  • BE-CO-HT section
  • Tomasz Wlostowski
  • Javier Serrano
  • Antonella Del Rosso
  • differential pair routing: support fast signals over a long distance and with less noise
  • length matching: two signals take exactly the same time to cross the PCB
  • Push and Shove router

[ESC]         = Cursor
[X]           = Track
[S]           = Set Origin
[SPACE]       = Set Relative Origin
[S]           = Set Grid Origin (manually set in menu "Dimensions" -> "Grid")

[PG UP]       = Switch to Front-Layer
[PG DOWN]     = Switch to Back-Layer
[V]           = Switch between Front and Back
[N]           = Switch Grid to Next
[SHIFT] + [N] = Switch Grid to Previous

Add tracks and vias (wiring):
[Backspace]   = Delete node

Interactive Router (OpenGL):

[X]           = Change to wiring mode
[Left Click]  = Select segment
[U]           = Select trivial connection
[I]           = copper connection

Move exactly

Only available in OpenGL canvas!

“Move exactly” for block selection in pcbnew?

Panelize / Append

Start Pcbnew (stand-alone), not via KiCad!

The “File -> Append Board” menu item is disabled, LAYOUT FILES: KiCad footprints useful for PCB panelization (mouse-bites…), Tools to load/edit/create/panelizer sets of gerber files

pointer tool
fiducial tool
enable high contrast
(like hiding all other layers!)
