Library for working with KiCAD file formats

Project description

# Routines for generating and parsing KiCAD files

There are multiple python scripts that read and write kicad file
formats. Currently there is the problem that each project reimplements
basic parsing and serialization of these formats.

The aim of this project is to provide high quality and well tested
format support so that other projects can focus on the interesting
stuff.


## Usage
```python
from pykicad.pcb import *
from pykicad.module import *

vi, vo, gnd = Net(1, 'VI'), Net(2, 'VO'), Net(3, 'GND')

r1 = Module.from_library('Resistors_SMD', 'R_0805')
r2 = Module.from_library('Resistors_SMD', 'R_0805')

r1.pads[0].net = vi
r1.pads[1].net = vo
r2.pads[0].net = vo
r2.pads[1].net = gnd

pcb = Pcb()
pcb.modules += [r1, r2]
pcb.nets += [vi, vo, gnd]

with open('project.kicad_pcb', 'w+') as f:
f.write(str(pcb))
```


## Supported file formats

* Modules (*.pretty, *.kicad_mod) in module.py
* Pcbnew (*.kicad_pcb) in pcb.py


# API docs
