This repository provides symbol libraries to generate electrical/electronic circuit schematics. The libraries are stored in simple .odg (Open Document Graphic) files, which are compatible with programs supporting the Open Document Format (ODF) standard (ex: OpenOffice, LibreOffice).

A more advanced alternative with even higher quality, configurable symbols is available in the form of an Inkscape plugin. I do not know the author, but I like the approach taken:

• inkscapeCircuitSymbols ↪: Analog components (R, L, C, transistors, sources, etc).
• inkscapeLogicGates ↪: A seperate plugin, for some reason.
• Also annotates the symbols (voltage, current flow, etc).
• Issue: 😕 Symbols are large relative to typical use case in a document (default scale). Is it possible to make them smaller by default?

To ease the process of positionning & connecting schematic symbols, it is highly suggested you modify the grid settings by following these steps:

1. Create a new drawing.

2. In Tools|Options...|LibreOffice Draw|General:

   • Set Unit of measurement = Millimeter.

3. In Tools|Options...|LibreOffice Draw|Grid:

   • Select Snap to grid & Visible grid.
   • Set Resolution (H&V) = 10mm (coarse resolution).
   • Set Subdivision (H&V) = 5 (Target: 2mm fine resolution).
   • Snap ⇒ Select nothing.
   • Snap position ⇒ Only check When rotating - set to 90deg.

4. In Format|Styles and Formatting:

   • Right-click on Default & click on Modify.
   • Set Width = 1mm.
