kicad-make

Makefile for building a board revision. I've used the generated files with JLCPCB, Screaming Circuits, and OSHPark.

Features

Runs DRC & ERC. If these do not pass than the manufacturing files won't be generated.
Includes both generic and JLCPCB targeted outputs

Generated Files

PDF Schematic
SVG board outline (edge cuts)
Gerbers w/ drill file & zipped gerbers
Interactive HTML BOM
STEP model of board
centroid w/ KiCAD and JLCPCB format
Full BOM and JLCPCB version

Notes

Semantic Versioning

We encourage using semantic numbering for board revisions. See the blog post https://www.maskset.net/blog/2023/02/26/semantic-versioning-for-hardware/ for the versioning scheme. As rolling the patch number ({Major}.{Minor}.{Patch}) is done to reflect BOM or manufacturing changes then the released board files will only be tied to the major & minor number. To reflect this we use {Major}.{Minor}.X as the board revision. You can use any version number you want though.

IBOM Version Number

The IBOM script uses the version number in the PCB title block in the filename. Note that this may be different than the declared version. We left this as your version should be the same and this acts as an easy indication you have a version issue.

Usage

You can copy or symlink the makefile into your project however I prefer to point to the file directly with makes -f command. The only usage requirements are:

All dependencies need to be on your path
make is called from the project directory
make finds the Makefile

Create a board revision

This is the default target and generates everything.

make -f kicad-make/Makefile PROJECT=<name of kicad project> REVISION=<revision number>

Skip DRC Check

Try to not do this too often... Exports everything, skipping ERC and DRC check.

make -f kicad-make/Makefile PROJECT=<name of kicad project> REVISION=<revision number> no-drc

Export schematic

make -f kicad-make/Makefile PROJECT=<name of kicad project> REVISION=<revision number> schematic

Example Usage

>> ls
project.kicad_pro   project.kicad_sch   project.kicad_pcb   project.kicad_prl

>> make -f kicad-make/Makefile PROJECT=project REVISION=0.1.X

>> ls
project.kicad_pro   project.kicad_sch   project.kicad_pcb                   project.kicad_prl
project_0.1.X.zip   project_0.1.X.pdf   project_0.1.X_interactive_bom.html  fab

FIXME

Add gerber PDF
- pypdf
Add mechanical drawing
Add renders of board top and bottom
