Part artwork and data in this folder
====================================

The part images (parts/svg/*.svg) and the part descriptions (parts/parts.json) come from two
Fritzing part libraries:

    https://github.com/fritzing/fritzing-parts    (c) the Fritzing project and the part authors
    https://fritzing.org
    (source="core" and source="contrib" entries in parts.json)

    https://github.com/adafruit/Fritzing-Library   (c) Adafruit Industries
    https://adafruit.com
    (source="adafruit" entries in parts.json — Adafruit's own parts, breakout boards, Feathers,
    LED backpacks, etc.; unzipped from their .fzpz bundles)

Both state they are licensed under Creative Commons Attribution-ShareAlike 3.0 Unported:
    http://creativecommons.org/licenses/by-sa/3.0/

This folder is therefore also licensed under CC BY-SA 3.0. You may reuse it, including commercially,
if you credit Fritzing and/or Adafruit (and the original part authors), keep this notice, and share
adaptations under the same licence. Adafruit's README asks that this also be noted: their library is
provided for educational purposes and they do not guarantee the correctness of any part.

Where fritzing-parts/contrib held an older mirror of the same Adafruit part (same title, usually an
older re-export), the build keeps only the Adafruit library's copy; a part already used in a saved
circuit is always kept as-is so existing circuits don't break.

Changes made to the original files (adaptations)
------------------------------------------------
- Only the breadboard view of each part is kept (schematic, PCB and icon views are dropped).
- parts.json is generated from the .fzp files: title, family, package, tags, and the list of
  breadboard connectors. Duplicate parts (same title and identical picture, or same title re-exported
  by both libraries) are merged, and parts without breadboard connectors are left out.
- SVG fixes for browsers: decimal commas ("5,006") turned into dots, and a display:none attribute
  removed from the group holding the breadboard layer.
- Resistor variants (100, 330, 1k, 4.7k, 10k, 100k, 1M ohm) are the 220 ohm resistor image with the
  colour bands changed.
- parts/custom.json: two ESP32-S3 SuperMini boards (breadboard view SVGs) that were downloaded
  separately from either library. Their author and licence were not recorded: check the source
  before redistributing them.

Circuits drawn with Plot Circuits and exported as images embed this artwork: credit Fritzing and
publish those images under CC BY-SA 3.0 as well (the SVGs produced by the render API already carry
this credit in their metadata).
