## Corax56 vs Corax54

I initially designed the Corax56 (=56 keys) with 4 pinky keys. The upper key (usually mapped to ESC) was placed in a new column because I found it easier to reach horizontally than vertically.
Over the time, I realized that I am not using this button very often. The Corax54 was born as a more compact version where the pinky cluster misses this additonal column and has only 54 keys (2 less). This is the only difference between the two versions.

## Firmware

Natively supports [ZMK](https://zmk.dev/). 
A ZMK module that supports both the Corax56 and Corax54 can be found [here](https://github.com/dnlbauer/zmk-keyboards-corax).

My personal firmware build is available at [https://github.com/dnlbauer/corax-zmk-config](https://github.com/dnlbauer/corax-zmk-config).
