CodeBoard

A keyboard specially made for coding with quicker access to common characters. After making CodePad I figured the next logical thing to do was to make a full keyboard for coding.

Layout

I chose this layout so that I could keep the normal keyboard layout while also optimizing for coding. It has keys I often use while coding to the right of the main part of the keyboard, similar to a numpad but for coding. The brackets and quotes type both characters and put the curser between the characters. The angle brackets don't because they are more commonly used for conditions rather than brackets in coding.

I wrote the firmware using KMK.

Case

The case consists of 3 parts: the bottom, the plate, and the top part. It uses M3x16mm screws and heat-set inserts to hold the 3 parts together.

Heres an assembly of the case:

I made the case using OnShape.

I made the PCB on KiCAD and learned how to create a key matrix.
