Keyboard PCB Guide
A step-by-step guide to designing custom keyboard PCBs using KiCad, covering schematics, component placement, routing, and production.
What is Keyboard PCB Guide?
Keyboard PCB Guide is a tutorial that teaches how to design custom printed circuit boards for mechanical keyboards using KiCad. It covers the entire workflow from schematic creation and component placement to routing traces and preparing files for manufacturing. The guide solves the problem of getting started with keyboard PCB design by providing a concrete, example-driven walkthrough.
Mechanical keyboard enthusiasts, DIY electronics hobbyists, and makers who want to create custom PCBs for their keyboard projects. It's aimed at beginners with little to no prior PCB design experience.
Developers choose this guide because it's specifically tailored to keyboard design, uses open-source tools (KiCad), and provides a complete end-to-end tutorial with recommended libraries and component sources. It demystifies the PCB design process with practical, visual examples.
Overview
Guide on how to design keyboard PCBs with KiCad
Use Cases
Best For
- Learning PCB design from scratch for mechanical keyboards
- Creating custom layouts for unique keyboard cases
- Prototyping small-batch keyboard PCBs for personal use
- Understanding how to route a switch matrix and microcontroller
- Generating production-ready Gerber files for manufacturers
- Sourcing components for a keyboard PCB build
Not Ideal For
- Experienced PCB designers seeking advanced techniques for large or complex keyboard layouts
- Projects using microcontrollers other than the ATmega32U4, such as STM32 or RP2040-based designs
- Designs requiring features like RGB backlighting, hot-swap sockets, or multi-layer PCBs
- Teams needing an end-to-end workflow that includes firmware development or collaborative version control
Pros & Cons
Pros
Walks through the entire PCB design process from schematics to Gerber files with detailed instructions and visual examples, such as the crystal routing and switch matrix setup.
Recommends specific open-source KiCad libraries like Hasu's keyboard_parts and techieee's keebs.pretty, which are optimized for keyboard parts and save time on footprint creation.
Includes clear steps for generating Gerber files and suggests PCB manufacturers like PCBWay, making it easy to transition from design to physical board production.
Provides direct DigiKey links for all electronic components, such as the ATmega32U4 and SMD capacitors, reducing the hassle of part selection and procurement.
Cons
Focuses on a basic 2x2 matrix example, lacking guidance on larger layouts, indicator LEDs, or mounting hole design, which are essential for most custom keyboards.
Requires downloading and configuring third-party KiCad libraries manually, which can be error-prone and confusing for beginners without prior experience in PCB tool setup.
Stops at PCB design without addressing how to program the microcontroller or integrate with keyboard firmware like QMK, leaving users to find separate resources for software development.
