Sinc - Split Staggered 75% Keyboard

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

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.

Now available! Rev. 2 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.

Acrylic Case available here: Sinc Acrylic Case

Features

• Option for rotary encoders at top left and top right corners
• ANSI/ISO support

• Due to a mistake made on the Rev. 1 PCBs, an Inverted-T arrow cluster on a 60% can't be done since the UP key is in the wrong location and can't be used (65% is fine)

• In-switch LED support (single-color 2-Pin LEDs)
• Separately controlled Caps Lock LED
