# JLCPCB Parts Integration - Complete Guide
## Overview
The KiCAD MCP Server integrates with JLCPCB's parts library to provide intelligent component selection, cost optimization, and automated part sourcing for PCB assembly.
**Current Implementation**: Uses the **JLCSearch public API** (by tscircuit) for free, unauthenticated access to JLCPCB's ~100k parts catalog.
## Features
**Parametric Search** - Find components by specifications (resistance, capacitance, package, etc.)
**Price Comparison** - Compare Basic vs Extended library pricing
**Alternative Suggestions** - Find cheaper or higher-stock alternatives
**Footprint Mapping** - Automatic JLCPCB package to KiCad footprint mapping
**Stock Availability** - Real-time stock levels from JLCPCB
**No Authentication Required** - Public API, no API keys needed
## Quick Start
### 1. Search for Components
```python
from commands.jlcsearch import JLCSearchClient
client = JLCSearchClient()
# Search for resistors
resistors = client.search_resistors(
resistance=10000, # 10kΩ
package="0603",
limit=20
)
# Search for capacitors
capacitors = client.search_capacitors(
capacitance=1e-7, # 100nF
package="0603",
limit=20
)
# General component search
components = client.search_components(
"components",
package="0603",
limit=100
)
```
### 2. Get Part Details
```python
# Get specific part by LCSC number
part = client.get_part_by_lcsc(25804) # C25804
print(f"Part: {part['mfr']}")
print(f"Stock: {part['stock']}")
print(f"Price: ${part['price1']}")
print(f"Basic Library: {part['is_basic']}")
```
### 3. Database Integration
```python
from commands.jlcpcb_parts import JLCPCBPartsManager
# Initialize database
db = JLCPCBPartsManager() # Uses data/jlcpcb_parts.db
# Download and import parts (one-time setup)
client = JLCSearchClient()
parts = client.download_all_components()
db.import_jlcsearch_parts(parts)
# Search imported database
results = db.search_parts(
query="resistor",
package="0603",
library_type="Basic",
in_stock=True,
limit=20
)
```
### 4. Footprint Mapping
```python
# Map JLCPCB package to KiCad footprints
footprints = db.map_package_to_footprint("0603")
# Returns:
# [
# "Resistor_SMD:R_0603_1608Metric",
# "Capacitor_SMD:C_0603_1608Metric",
# "LED_SMD:LED_0603_1608Metric"

## Best Practices
### 1. Always Use Basic Library Parts First
Basic library parts have **no assembly fee** ($0/part), while Extended parts cost **$3/part**.
```python
# Filter for Basic parts only
basic_parts = [p for p in results if p['is_basic']]
```
### 2. Check Stock Availability
Ensure sufficient stock before committing to a design.
```python
# Only use parts with >1000 stock
high_stock = [p for p in results if p['stock'] > 1000]
```
### 3. Compare Prices
Even within Basic library, prices vary significantly.
```python
# Find cheapest option
cheapest = min(results, key=lambda x: x.get('price1', 999))
```
### 4. Use Standardized Packages
Stick to common packages (0402, 0603, 0805) for better availability and pricing.
### 5. Cache Database Locally
Download the full parts database once and search locally for faster results.
```python
# Initial download (one-time, ~5-10 minutes)
if not os.path.exists("data/jlcpcb_parts.db"):
parts = client.download_all_components()
db.import_jlcsearch_parts(parts)
# Subsequent searches use local database (instant)
results = db.search_parts(...)
```
## Troubleshooting
### API Rate Limiting
JLCSearch is a community service. If you hit rate limits:
- Add delays between requests (`time.sleep(0.1)`)
- Use the local database instead of repeated API calls
- Download the full database once and work offline
### Missing Data
JLCSearch may not have all fields that official JLCPCB API provides:
- No datasheets (use manufacturer website)
- Limited category information
- No solder joint count
### Stock Discrepancies
Stock levels are updated periodically but may lag real-time JLCPCB data by a few hours.
## Official JLCPCB API (Alternative)
The project also includes an implementation of the official JLCPCB API with HMAC-SHA256 authentication. However, this requires:
1. API approval from JLCPCB (not all applications are approved)
2. APP_ID, ACCESS_KEY, and SECRET_KEY credentials
3. Previous order history with JLCPCB
To use the official API instead of JLCSearch:
```python
from commands.jlcpcb import JLCPCBClient
# Set credentials in .env file:
# JLCPCB_APP_ID=<your_app_id>
# JLCPCB_API_KEY=<your_access_key>
# JLCPCB_API_SECRET=<your_secret_key>
client = JLCPCBClient(app_id, access_key, secret_key)
data = client.fetch_parts_page()
```
**Note:** Most users should use JLCSearch public API instead, as it's freely available and requires no authentication.

# Schematic Workflow Fix - Issue #26
## Problem Summary
The schematic workflow was completely broken due to incorrect usage of the kicad-skip library:
1. **`create_project`** only created PCB files, no schematic
2. **`create_schematic`** created orphaned schematic files not linked to projects
3. **`add_schematic_component`** called non-existent `schematic.add_symbol()` method
4. Project files didn't reference schematics in their structure
## Root Cause
The kicad-skip library **does not support creating symbols from scratch**. The only way to add symbols is by **cloning existing symbol instances**.
From kicad-skip documentation:
> "symbols: these don't have a new()" because they require complex mappings to library elements, pins, and properties.
## Solution
### 1. Template-Based Approach
Created a template schematic (`python/templates/template_with_symbols.kicad_sch`) with:
- Complete `lib_symbols` section defining R, C, LED symbols
- Three template symbol instances placed off-screen at (-100, -110, -120)
- Template symbols marked as `dnp yes`, `in_bom no`, `on_board no` so they don't interfere
### 2. Updated Files
**python/commands/project.py:**
- Now creates both `.kicad_pcb` AND `.kicad_sch` files
- Project file includes schematic reference in `sheets` array
- Copies template schematic with cloneable symbols
**python/commands/schematic.py:**
- Uses template file instead of creating from scratch
- Proper minimal schematic structure when template unavailable
**python/commands/component_schematic.py:**
- Completely rewritten to use `clone()` API
- Maps component types to template symbols
- Proper UUID generation for each cloned symbol
- Correct position setting: `symbol.at.value = [x, y, rotation]`
### 3. Correct Workflow
```python
from commands.project import ProjectCommands
from commands.schematic import SchematicManager
from commands.component_schematic import ComponentManager
# Step 1: Create project (creates both PCB and schematic)
project_cmd = ProjectCommands()
result = project_cmd.create_project({
"name": "MyProject",
"path": "/path/to/project"
})
# Step 2: Load the schematic
sch = SchematicManager.load_schematic(result['project']['schematicPath'])
# Step 3: Add components by cloning templates
component_def = {
"type": "R", # Maps to _TEMPLATE_R
"reference": "R1", # Component reference
"value": "10k", # Component value
"footprint": "Resistor_SMD:R_0603_1608Metric",
"x": 50.8, # Position in mm
"y": 50.8, # Position in mm
"rotation": 0 # Rotation in degrees
}
symbol = ComponentManager.add_component(sch, component_def)
# Step 4: Save the schematic
SchematicManager.save_schematic(sch, result['project']['schematicPath'])
```
## Supported Component Types
Currently supported template symbols:
- `R` - Resistor (maps to `_TEMPLATE_R`)
- `C` - Capacitor (maps to `_TEMPLATE_C`)
- `D` or `LED` - LED (maps to `_TEMPLATE_D`)
To add more component types, update:
1. `python/templates/template_with_symbols.kicad_sch` - Add lib_symbol definition and template instance
2. `python/commands/component_schematic.py` - Add mapping in `TEMPLATE_MAP`
## Testing
Comprehensive test created at `/tmp/test_schematic_workflow.py`:
- Creates project with schematic
- Loads schematic
- Adds R, C, LED components
- Saves schematic
- Validates with `kicad-cli sch export pdf`
All tests passing ✓
## Files Modified
- `python/commands/project.py` - Added schematic creation
- `python/commands/schematic.py` - Fixed template usage
- `python/commands/component_schematic.py` - Rewritten to use clone() API
- `python/templates/empty.kicad_sch` - Minimal template (created)
- `python/templates/template_with_symbols.kicad_sch` - Template with cloneable symbols (created)
## Limitations
1. Can only add components that have templates defined
2. Template symbols remain in schematic (but marked as DNP/not in BOM)
3. Complex symbols (multi-unit, hierarchical) may need custom templates
## Future Improvements
1. Add more component templates (transistors, connectors, ICs)
2. Dynamic template generation from KiCad symbol libraries
3. Auto-hide template symbols in schematic
4. Support for custom user templates
