A step-by-step guide to designing custom keyboard PCBs using KiCad, covering schematics, component placement, routing, and production.
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.
Guide on how to design keyboard PCBs with KiCad
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
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.
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.
