The Helix keyboard is a split ortholinear design that features a 5x6 grid with two additional thumb keys on the bottom two rows. 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 PCBs allow for hotswapping of keyboard switches via Kailh MX Hotswap Sockets. These sockets are compatible with Cherry MX style switches.

The Helix keyboard was originally designed by pluis9 with artwork by void_keys and was remixed by mcmadhatter in order to add hotswap functionality. Additional information about the Helix keyboard along with the source files from the designer can be found on the Helix Hotswap Github repository. QMK key mappings and firmware can be found here.
