Go split. Keep your arrow keys.
A Split Keyboard Without the Compromises
Split the keyboard you already know instead of learning a new one.
Keep the keys you actually use
Most split keyboards drop the function row, the arrow keys, or both, and hide them on layers. Sinc keeps a 75% layout with F-keys and arrows. Quefrency keeps a 65% layout with arrows.
Nothing to relearn
Both use a staggered layout, the same row offset as the keyboard you type on now. Your fingers land where they expect, so the only change is moving the halves apart to where your hands are comfortable.
Extra keys if you want them
Add the optional 2x5 macro section on the left half for shortcuts, and remap any key with QMK and VIA. No account and no special software needed to type.

Want It Thinner? Go LM.
Same layouts, low-profile build.
LM means low-profile
Sinc LM and Quefrency LM are the same layouts in a thinner build, so your hands sit lower and flatter on the desk.
Choc low-profile switches
LM boards are designed for Kailh Choc V2 low-profile switches, with hotswap sockets so you can change them without soldering.
Standard key spacing
The keys keep standard MX spacing, so the LM feels like the keyboard you know, just thinner.
What Owners Say
From real customer reviews.
"I started with an ErgoDox and used it for years, but the biggest improvement I've found for ergonomics is not the layout of the keys, but just being able to split the keyboard. I'm actually a bit glad to return to a standard QWERTY layout. … The hotswap option just lets you jump right in. … This is probably the best keyboard I've ever experienced."
"I've built three of these now in assorted generations of PCB and they are all great. I love the rotary dials and the full-sized split board (I can't lose my function keys)."
"I love my Sinc so much for gaming. Most of the day I keep both halves out, but I can stash away the right half and get back so much mouse room it's insane."
