1. More than one typing feel option(1) PCB Gasket(plateless): bounce; (2) Gasket: a little bounce; (3) Top: stiff The method to realize it is to use a specially designed middle frame.
Turn over the middle frame to clamp PCB or plate with gaskets, so that we are able to switch between PCB gasket, gasket and top. For PCB Gasket, the FR4 plate ear needs to remove;
For Gasket Mount/Top Mount, the PCB ear needs to remove (it’s irreversible)(1)PCB Gasket → Gasket (By turning over the middle frame), below shows how it works.
(2)Top mount (The plates have screws holes for top mount)
2. Interchangeable type-c connector and decorationSomeone like left type-c and someone like right one, so we designed a type-c connector that can place left or right as you like. Appearance DesignAs the studio manager's name is Chain Smoker, and we want to make the keyboard more distinctive, so we add some cigarette elements to it.
Although we used some cigarette elements, we do not encourage smoking, so we engraved “ Smoking is harmful to health” inside the bottom case for reminding.
