About the Thesplit PCB

Thesplit is an open source PCB design by jeffdhooton, published on GitHub. It is a 2-layer board measuring 298.3 × 123.3 mm, with 78 components from 4 distinct parts.

By type, the board carries 38 switches, 38 diodes and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

38-key ergonomic keyboard

This is an ergonomic, 38-key, VIAL compatible keyboard based off of the corne/crkbd but with a larger column stagger. I designed the board to be hotswap, and use cheap SMD components, and a 3D printed case.

You will need all of the following to build one of these boards.

1. PCBs from a PCB manufacturer (JLCPCB cost me $18 for 5 of these boards)

Once you receive your PCBs in, and have all of your components - you're ready to build. Building this board should be pretty straight forward for anybody that's done so for other boards before. If you haven't, then the build process is as follows:

Thesplit: common questions

How big is the Thesplit PCB?

The Thesplit measures 298.3 × 123.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Thesplit?

78 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Thesplit design files?

From the jeffdhooton/jingis38 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Thesplit design in my own project?

The repository has no license, so all rights stay with jeffdhooton. Use it as a reference, and ask the author before reusing the design.
