Know before you buy
The full isolation system sandwiches the plate between rubber gaskets, ensuring it never makes direct contact with the case. This design significantly reduces vibration and creates a more consistent, cushioned feel across every keypress.
Yes, the kit is compatible exclusively with MX-style mechanical switches. You will need to source these separately as they are not included in the kit.
Both plates are crafted from durable 5052 material with a sandblasted finish, but they offer different acoustic and tactile profiles. Aluminum typically provides a stiffer, more resonant typing experience, while Forged Carbon tends to be slightly more muted and flexible.
Yes, the PCB supports an optional encoder in the top-left corner. You will need to purchase the encoder separately and solder it into the designated spot on the DSP40 PCB.
No, the board only supports single-color in-switch LEDs. You will need to solder individual LEDs to the board to enable backlighting.
The Gravestone-40 uses a standard USB-C interface. Any high-quality USB-C cable will work for both data transmission and power.
