Bill of Materials (BOM)
ProtoFlow automatically generates a Bill of Materials from your schematic with component grouping, LCSC pricing lookup, volume tier pricing, and CSV export.
# Generating a BOM
Generate a BOM from the toolbar or by asking the AI Copilot.
How to Generate
- Click the BOM button in the toolbar, or open the BOM panel from the activity bar
- ProtoFlow scans the current schematic and groups components by value
- The BOM dialog opens showing all components with quantities
BOM Contents
The generated BOM includes:
| Column | Description |
|---|---|
| Reference | Component reference designators (e.g., R1, R2, R3) |
| Value | Component value (e.g., 10kΩ, 100nF) |
| Quantity | Number of instances of this component |
| Footprint | Package/footprint (e.g., 0402, 0603, SOIC-8) |
| LCSC Part # | LCSC part number if available |
| Unit Price | Price per unit from LCSC or manual entry |
| Total Price | Quantity × Unit Price |

# LCSC Pricing Lookup
For components sourced from LCSC, ProtoFlow can automatically look up current pricing including volume discount tiers.
Features
- Automatic price lookup — Components with LCSC part numbers get pricing fetched automatically
- Volume tiers — See pricing for different quantities (1pc, 10pc, 100pc, 1000pc)
- Stock status — Real-time stock availability from LCSC
- Manual pricing — Enter prices manually for components not sourced from LCSC
- Total cost calculation — Automatic calculation of total BOM cost based on quantities and prices

# Exporting the BOM
Export your BOM to CSV for use in spreadsheets, procurement tools, or sharing with your team.
Export Options
- CSV export — Standard comma-separated values format, compatible with Excel, Google Sheets, and procurement platforms
- Grouped by value — Components are grouped by value, with reference designators listed in each row
- Includes pricing — Export includes unit pricing and total cost columns
Click the Export button in the BOM dialog to save the CSV file to your computer.
