The Helix keyboard is a split ortholinear design that features a 5x6 grid with two additional thumb keys on the bottom two rows. This keyboard design is one of the first well known split keyboards to come from Japan. Many of the innovations introduced by the Helix were carried over into other layouts like the Lily58 and Corne keyboards. The PCBs feature per key RGB lighting as well as footprints for optional OLED screens. By default, the screens display the current layer and information about recently pressed keys. The bottom row of the PCB can also be broken off in order to create a four row layout.

The Helix keyboard was designed by pluis9 with artwork by void_keys. Additional information about the Helix keyboard along with the source files from the designer can be found on the Helix Github repository. QMK key mappings and firmware can be found here.
