Tiny JLCPCB Tools for KiCad

Tools for KiCad for using JLCPCB's assembly-service.

jlcpcb-library.sh

Thin wrapper around the JLC2KiCadLib tool (https://github.com/matthewlai/JLCKicadTools) that actually performs the downloading and conversion.

This adds functionality to read parts from a file, automatically setting SMT attribute if needed, plus an optionaal patch system for fixing footprint files.

Usage:

jlcpcb-library.sh <parts-file> <library name> [patches dir]

Example invocation, creating the directory Foo containing the schematics library and footprint library:

jlcpcb-library.sh foo-parts.txt Foo foo-patches

Note: the library will be overwritten each time, so don't make any changes to the files after running the tool -- use the patches system.

parts-file

Contains Cxxxxx LSC part numbers, one per line. Comments are allowed and start with '#', eiter on a separate line or the same row.

Example:

# 5V-regulator
C97643 # (E) Step-down 4,75-40V 1A SOT-23-6
# Connectors
C2897378 # EXTENDED 5 pin female socket header 2,54 through hole.

library-name

Name of the library in KiCad, and also the filename.

Example: AwesomeProject

patches-dir

Optional directory of patches for the footprint files (`.kicad_mod`` files), for fixing e.g. wrong placement.

Example:

AwesomeProject-patches:
    PG-DSO-8_L5.0-W4.0-P1.27-LS6.0-BL.kicad_mod.patch

Contents of PG-DSO-8_L5.0-W4.0-P1.27-LS6.0-BL.kicad_mod.patch - a fix for 3D model placement on footprint:

jlcpcb-postprocess.py

For use with the KiCad JLCPCB fabrication toolkit generating a production directory w/ fabrication data. Processes BOM file and positions file to match the JLCPCB input format.

Usage:

jlcpcb-postprocess.py <path/to/production>

Processes the files in the production directory: bom.csv and positions.csv. The files are overwritten.
