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. A ZMK module that supports both the Corax56 and Corax54 can be found here.

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