Getting Started
- Open the project in KiCad 6.0 or later
- Review the schematic in the schematic editor
- Open the PCB layout to see the board design
- Generate Gerber files for manufacturing:
- File → Fabrication Outputs → Gerbers (.gbr)
- File → Fabrication Outputs → Drill Files (.drl)
Manufacturing Notes
This board design follows standard specifications that are compatible with most PCB manufacturers including OSHpark and PCBway. The design uses:
- Standard 2-layer stackup
- Minimum features well within typical manufacturing capabilities
- PTH components only (no SMD components)
- Clear silkscreen markings
- Proper board outline on Edge.Cuts layer

Questions
How big is the Small pth board PCB?
It measures 80 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Small pth board use?
3 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Small pth board KiCad files?
From the markhu/pcb-markhu repository on GitHub, at the commit this page was made from: the board is small-pth-board.kicad_pcb and its schematic small-pth-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Small pth board design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
