Sinc Rev. 3 PCB Kit - Split Staggered 75% Keyboard


Sign up to be notified when this is restocked!

Split 75% keyboard with optional 2x5 macro section and right column.

Coming Soon! Rev. 3 PCBs: TRRS jacks for connecting both halves have been replaced with USB-C! This will allow for a slimmer build with shorter standoffs and less of a chance of shorting out PCBs while disconnecting halves from each other.

PCB Kits and Plate Kits are sold separately, so unless you are having your own case/plates made, you will need both a PCB kit and Plate kit.
