Cepstrum - Choc Low-Profile 65%/65XT Split Staggered Keyboard Kit


A 65%/65XT split staggered keyboard, with 2x5 macro section option for the left half. Just like the Quefrency, but this time, low-profile! This board features hotswap sockets for Choc Low-Profile switches and per-key RGB LEDs. Cepstrum is pronounced as KEP-strum.
