Crosshatch - 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.

PCB render

  • 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.

Ordering PCBs

PCBs can be manufactuered by a variety of online PCB fabricators. You can use PCBShopper to search for the best price.

The zip file in the gerber directory contains the gerber files your fabricator will need to make the PCB lumberjack.zip PCB.

When uploading the gerber zip files, use the default PCB settings.
