Alexa innovates on typing comfort with leaf-spring top mount, PCB gasket mount, support for plateless configurations, and a comfortable 16.5 mm front height. The Alexa PCB also features in-browser keymap customization with Remap, and comes with glued down 2nd generation Kailh hotswap sockets for resistance against wear and damage from repeated switch insertions.
Improving upon Scarlet's design, Alexa's front height has been reduced by 12% to just 16.5 mm — all while retaining the high profile case design. A center aligned USB-C daughterboard provides a neutral cable position with a larger cable cutout for improved cable compatibility, and the thin side bezels give the keyboard a slim profile.
As keyboards trend towards softer typing experiences, Alexa pushes the limits with a 1.2 mm thin PCB secured to the case using gasket mount or leaf-spring top mount for a remarkably flexible and bouncy typing experience. And because the PCB is used for mounting, the plate can be removed altogether resulting in the most comfortable keyboard we've ever made.
The PCB is sandwiched by the case from above and an ultra-soft poron gasket below, absorbing keystroke vibrations for a muted sound and softer typing experience.
Leaf-spring top mount.
Screws fasten the PCB to the top case, and leaf-springs eliminate stiffness from the screws for a consistent and bouncy feel across the whole keyboard.
The Alexa hotswap PCB features 2nd generation Kailh hotswap sockets with stronger leaves that maintain contact after many switch insertions, and glued down to resist being broken off the PCB. Half plate and plateless configurations have been tested with switches remaining secured to the PCB after months of continuous use. 5-pin switches are recommended for stability, and a solder PCB will be available for extra layout compatibility and plateless stability.
Each kit includes an FR4 plate for those who prefer a firmer typing experience, as well as improved switch alignment and stability when assembling with 3-pin switches. A POM plate is available as an add-on for a deep, rich sound signature, and soft typing experience.
