# This is a version of szczys's kicad-to-neoden, modified for use by the FemtoStar Project, so as to output the

# format expected by the Neoden 3V we use. We admit - it's kind of hackish, and remains a work in progress.

# Right now, this is not likely to work with negative X coordinates in the inputs, but will handle negative Y, which
|

|
# KiCAD's .pos files use for objects in the +X/YY quadrant of the board in KiCAD's coordinate system.
|

|
|
# This matches the quadrant KiCAD displays the page layout in, and so should usually be correct.
