AidanBrzezinski KiCad Library
Personal KiCad component library used as a git submodule across all projects. All symbols, footprints, and 3D models are verified against manufacturer datasheets.
Usage
Add to a project as a git submodule:
git submodule add https://github.com/AidanBrzezinski/KiCad_Library lib/shared
git submodule update --init --recursive
When cloning a project that uses this library:
git clone --recurse-submodules https://github.com/AidanBrzezinski/YourProject
Register libraries in KiCad using the included sym-lib-table and fp-lib-table files,
or add manually via Preferences → Manage Symbol/Footprint Libraries → Project Libraries.
Always use ${KIPRJMOD}/lib/shared/... as the path prefix.

Symbols
- All symbols copied from KiCad global library retain the original drawing unchanged
- Only fields are modified — never pin positions, body size, or pin length
- Custom drawn symbols follow KiCad standard: 100mil pin length, 1.27mm text size
- Fields set on every symbol:
| Field | Example | Notes |
|---|---|---|
| Value | SN74HC193DR |
Full MPN including package suffix |
| Footprint | 0_package_SO:SOIC-16_3.9x9.9mm_P1.27mm |
Points to library footprint |
| Datasheet | ../../Datasheets/SN74HC193.pdf |
Local relative path |
| MPN | SN74HC193DR |
Exact manufacturer part number |
| Digikey_PN | 296-1191-1-ND |
Digikey part number at time of addition |
| Manufacturer | Texas Instruments |
Manufacturer name |
| Library_Source | KiCad 8.0 global 74xx lib |
Where symbol drawing came from |
Footprints
- All footprints verified against physical datasheet dimensions
- Courtyard, silkscreen, fab, and copper layers all present
- 3D model linked via
${KIPRJMOD}/lib/shared/3d_models/PartName.step - Pad numbering matches symbol pin numbering exactly
3D Models
- Stored flat in
3d_models/— no subfolders - Named by MPN e.g.
SN74HC193DR.step - Referenced in footprints via
${KIPRJMOD}/lib/shared/3d_models/ - Source noted in footprint description field (SnapEDA, manufacturer, KiCad built-in)
Datasheets
- One PDF per unique MPN, named exactly by MPN e.g.
SN74HC193.pdf - Symbol Datasheet field points to local relative path
- Do not commit datasheets for parts with stable public URLs if file size is a concern
Git Commits
- One component per commit where possible
- Commit message format:
lib: add SN74HC193DR symbol footprint and datasheet - Library structure changes committed separately from component additions
