What This Skill Does

The KiCad PCB Automation skill empowers users to streamline the entire Printed Circuit Board (PCB) design and manufacturing process using the powerful and open-source KiCad software. This skill acts as a bridge, allowing you to translate natural language descriptions into functional circuit schematics, design PCB layouts, perform design verification, and generate manufacturing-ready files. It further integrates with PCBWay to provide instant quotes and facilitate the ordering process, creating a seamless design-to-prototype-to-manufacture pipeline.

Key functionalities include:

• Schematic Design: Creating circuit schematics from textual descriptions of components and their connections.
• PCB Layout: Designing the physical board layout, including component placement and routing.
• Verification: Running Electrical Rules Checks (ERC) and Design Rule Checks (DRC) to ensure design integrity and compliance with manufacturing standards.
• File Export: Generating essential manufacturing files such as Gerber files, drill files, Bill of Materials (BOM), and pick-and-place files.
• Manufacturing Integration: Interfacing with PCBWay for instant quoting and order placement.

Installation

To install the KiCad PCB Automation skill, you will need to have KiCad and its associated Python dependencies installed on your system. Follow these steps:

1. Install KiCad:

For Ubuntu/Debian systems:

sudo add-apt-repository ppa:kicad/kicad-8.0-releases
sudo apt update
sudo apt install kicad

Verify the installation by running:

kicad-cli --version

2. Install Python Dependencies:

Navigate to the skill's directory and run:

pip install pillow cairosvg

Then, install the skill itself:

clawhub install openclaw/skills/skills/g0head/kicad-pcb

Use Cases

• Hobbyist Electronics: Quickly prototype new electronic circuits by describing them in plain language and automating the PCB design steps.
• Educational Projects: Students can learn PCB design principles by using the skill to create and iterate on circuit designs.
• Small-Scale Manufacturing: Generate all necessary files for producing custom PCBs for small batches of products.
• Rapid Prototyping: Design and order prototypes rapidly by leveraging the integrated PCBWay quoting system.
• Automating Repetitive Tasks: For engineers who frequently design similar circuits, this skill can speed up the initial setup and design phases.

Example Prompts

1. "Create a new PCB project called 'Simple Buzzer' for a basic buzzer circuit using a transistor and a 555 timer."
2. "Add a 10k Ohm resistor with the reference designator R1 and a ceramic capacitor of 100nF with C1 to the current schematic."
3. "Export all manufacturing files for the current project and get a quote for 10 boards from PCBWay."

Tips & Limitations

• KiCad Version: Ensure you are using a compatible version of KiCad (preferably KiCad 8 or later) as specified in the installation instructions.
• Component Naming: Use standard component names (e.g., NE555, LED, R 10K) and clear reference designators for accurate schematic generation.
• Circuit Complexity: While the skill can automate many tasks, highly complex or specialized circuits may require manual adjustments in KiCad.
• PCBWay Authentication: For actions like adding to the PCBWay cart, you might need to handle authentication separately if not managed by the OpenClaw platform.
• Error Handling: Always review the output of commands, especially DRC and ERC checks, for any potential design issues that require manual intervention.
• File Paths: Be mindful of the current project directory. Commands operate within the context of the active project.
• Iterative Design: PCB design is often iterative. Use the preview-schematic and preview-pcb commands frequently to visualize changes and catch errors early.
