Sinc Rev. 4 PCB Kit - Split Staggered 75%/TKL Keyboard
$84.99Split 75% keyboard with optional 2x5 macro section. Now featuring hotswap sockets, so just pop in your switches, and you are good to go!
Rev. 4 vs. Rev. 3 PCBs:
- Added VBUS circuit for more reliable keyboard startup of each half when booting or waking up your computer
- Added a couple more layout options at thumb keys on the bottom row
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 (from the Case/Plates drop-down from above).
