Example placement
About the Example placement PCB
Example placement is an open source PCB design by snhobbs, published on GitHub under the LGPL-3.0 license. It is a 2-layer board measuring 57 × 87 mm, with 17 components from 15 distinct parts.
By type, the board carries 16 test points and 1 connector.
From the project
Auto place components into pcbnew from a centroid file. Useful for maintaining a common board form factor.
A schematic is drawn up with matching reference designators:
The schematic is exported to a PCB which will look like this:
Running the script on this board with this command exports the following board with the components exactly aligned ready for layout. The group can be treated as a footprint, placed where ever is useful. During layout you only have to deal with a single coordinate as the position within the group is locked.
