2.6 KiB

/hardware/bom

Bill of Materials for your KiCad project.

Purpose

This directory contains Bill of Materials (BOM) files generated from your KiCad schematic and additional BOM-related documentation.

File Types

  • .csv: Comma-separated values format (most common)
  • .xlsx: Excel spreadsheet format
  • .xml: XML format for automated processing
  • .html: HTML format for web viewing
  • .pdf: PDF format for documentation

Generating BOM from KiCad

  1. Open your schematic (.kicad_sch)
  2. Go to Tools → Generate Bill of Materials
  3. Select or configure a BOM plugin
  4. Set output directory to hardware/bom/
  5. Click Generate

Basic BOM (ProjectName-BOM.csv)

  • Reference designators
  • Values
  • Footprints
  • Quantities
  • Manufacturer part numbers
  • Supplier part numbers

Extended BOM (ProjectName-BOM-Extended.xlsx)

  • All basic information plus:
  • Descriptions
  • Manufacturer names
  • Supplier links
  • Pricing information
  • Stock availability
  • Alternative parts

BOM Structure Example

Reference | Value      | Footprint        | Qty | MPN           | Supplier | SPN
----------|------------|------------------|-----|---------------|----------|-------------
R1,R2,R3  | 10k        | R_0603_1608Metric| 3   | RC0603FR-0710KL| Digi-Key | 311-10.0KHRCT-ND
C1,C2     | 100nF      | C_0603_1608Metric| 2   | GRM188R71C104KA01D| Mouser | 81-GRM188R71C104KA1D
U1        | STM32F401  | LQFP-64_10x10mm  | 1   | STM32F401RET6 | Digi-Key | 497-11767-ND

BOM Management Best Practices

  • Include manufacturer part numbers (MPN)
  • Add supplier part numbers for purchasing
  • Include alternative/substitute parts
  • Document any special requirements
  • Update BOM with design changes
  • Version control BOM files
  • Include pricing and availability data

KiCad BOM Plugins

  • bom_csv_grouped_by_value: Groups components by value
  • bom_csv_sorted_by_ref: Sorts by reference designator
  • kibom: Advanced BOM generator with many options
  • InteractiveHtmlBom: Creates interactive HTML BOMs

File Naming Convention

Following FILE-NAMING-AND-VERSIONING.md standards:

  • project-name_bom_v1.0.0_2024-08-04.csv - Basic BOM
  • project-name_bom-extended_v1.0.0_2024-08-04.xlsx - Detailed BOM with pricing
  • project-name_bom-assembly_v1.0.0_2024-08-04.csv - Assembly-specific BOM
  • project-name_bom-production_v2.1.0_2024-08-04.csv - Production BOM

Versioning Strategy

  • MAJOR: Component changes affecting compatibility
  • MINOR: Component value changes, new optional components
  • PATCH: Documentation updates, supplier changes
