Coarse60 - Alu Leaf-Spring Alice for $210 | LIVE NOW

COARSE 60%



by sehonky + Keebsforall


A $210 Alice 60% with a premium experience.

Leaf-Spring Mounting (that actually works)!
A bouncy and energetic typing experience combined with a crisp, sound (without needing foam) is one of my favorite things about this board.

Typing Test: https://www.twitch.tv/videos/1158988347?t=01h45m09s

Aluminum Shell
Providing noticeable weight and premium feeling. Finished with a beautiful electrophoresis coating of white, navy, or black. (price is not raised from what it would be with anodization)



Multi-Layout Hotswap PCB + RGB Underglow
The PCB with the Coarse60 supports all alice positions with hotswap except split backspace (solder support), as well as full backspace, full right shift, both left spacebar positions, and stepped and normal caps lock with no interference (tested by Andy V Nguyen). It also has a row of downwards-facing RGB LEDs that will illuminate the frosted acrylic bottom.


Note: the final production PCB has top USB port.
QMK Support, VIA Support pending (will def be ready by the time you receive your board)

Note About Plates
If you want flex, go for aluminum. That is the only option with leaf-springs. POM is too flexible inherently, and not only can it not support leaf-springs, but requires extra mounting points. POM would be more desired for its sound. Neither plates are hollow sounding in our tested configurations (JWK linears or tactiles).

ALU PLATE


Middle mounting holes (circled in red) are optional, leaf-springs and acoustic cut.

POM PLATE


No leaf-springs or acoustic cuts, middle mounting holes required.

Concerns?
There was a concern that Andy V Nguyen brought up about bottoming out when typing roughly. We brought the keyboard's height up by an mm, shortened the leafsprings slightly, and are adding a foam sticker to the bottom of the PCB to address this concern. We'll keep you updated!

I hope you consider this board, I designed it myself and really do believe it is the best you can do with $210.

Have a good day.
