README.mdCrosshatch - Through-hole ortholinear 60% keyboard PCB
Crosshatch is a 12 column ortholinear keyboard PCB using through-hole components only.
The goal of this project is to build an all through-hole component ortholinear PCB that fits in a standard 60% tray mount case.
Inspired by the Plaid keyboard.
- Designed to be easy to build with minimal soldering experience.
- All through-hole components, no SMD soldering required.
- Get that visible component aesthetic in a standard 60% tray-mount case.
- Plateless.

Questions
How big is the Crosshatch PCB?
It measures 285.4 × 94.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Crosshatch use?
150 parts, built around the ATMEGA328-PU. 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 Crosshatch KiCad files?
From the peej/crosshatch-keyboard repository on GitHub, at the commit this page was made from: the board is crosshatch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Crosshatch design in my own project?
Its repository states no licence, so its author keeps all rights: ask peej before reusing the design.
