**Solution:**
|
||||
- Template schematic with cloneable R, C, LED symbols
|
||||
- Updated `create_project` to create both PCB and schematic
|
||||
- Rewrote `add_schematic_component` to use `clone()` API
|
||||
- Proper UUID generation and position setting
|
||||
|
||||
**Files Modified:**
|
||||
- `python/commands/project.py` - Now creates schematic files
|
||||
- `python/commands/schematic.py` - Uses template approach
|
||||
- `python/commands/component_schematic.py` - Complete rewrite
|
||||
|
||||
**Files Created:**
|
||||
- `python/templates/template_with_symbols.kicad_sch`
|
||||
- `python/templates/empty.kicad_sch`
|
||||
- `docs/SCHEMATIC_WORKFLOW_FIX.md`
|
||||
|
||||
**Testing:**
|
||||
- Created comprehensive test suite

|
||||
// Download database (one-time setup)
|
||||
await server.callTool("download_jlcpcb_database", {});
|
||||
|
||||
// Search for parts
|
||||
await server.callTool("search_jlcpcb_parts", {
|
||||
package: "0603",
|
||||
library_type: "Basic",
|
||||
limit: 20
|
||||
});
|
||||
|
||||
// Get part details
|
||||
await server.callTool("get_jlcpcb_part", {
|
||||
lcsc_number: "C25804"
|
||||
});
|
||||
|
||||
// Suggest alternatives
|
||||
await server.callTool("suggest_jlcpcb_alternatives", {
|
||||
lcsc_number: "C25804",
|
||||
limit: 5
|
||||
});
|
||||
```
|
||||
|
||||
### Direct Python Usage
|
||||
|
||||
```python
|
||||
from commands.jlcsearch import JLCSearchClient
|
||||
from commands.jlcpcb_parts import JLCPCBPartsManager
|
||||
|
||||
# Initialize
|
||||
client = JLCSearchClient()
|
||||
db = JLCPCBPartsManager()
|
||||
|
||||
# Search live API
|
||||
resistors = client.search_resistors(
|
||||
resistance=10000,
|
||||
package="0603",
|
||||
limit=20
|
||||
)
|
||||
|
||||
# Search local database
|
||||
results = db.search_parts(
|
||||
package="0603",
|
||||
library_type="Basic",
|
||||
in_stock=True,
|
||||
limit=20
|
||||
)
|
||||
|
||||
# Get footprints
|
||||
footprints = db.map_package_to_footprint("0603")
|
||||
# Returns: ["Resistor_SMD:R_0603_1608Metric", ...]
|
||||
```
|
||||
|
||||
## Authentication Journey
|
||||
|
||||
### Attempted: Official JLCPCB API
|
||||
1. Implemented HMAC-SHA256 signature authentication
|
||||
2. Built complete signature string (`METHOD\nPATH\nTIMESTAMP\nNONCE\nBODY\n`)
|
||||
3. Tested with user-provided credentials
|
||||
4. **Result**: 401 Unauthorized (requires approved API access)
|
||||
|
||||
### Solution: JLCSearch Public API
|
||||
1. Discovered community-maintained public API
|
||||
2. No authentication required
|
||||
3. Same data, simpler access
|
||||
4. Faster development iteration

# 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
