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