The Sinc LM is a low-profile variant of the Sinc keyboard! Reprogrammable to any keymap layout you'd like with QMK/VIA! We've worked up case parts for the Sinc LM PCB series that offer a more premium feel than other ergo split keyboard offerings.
The Sinc LM is a great ergonomic keyboard for newbies! This kit is easy to assemble with the hotswap sockets on the PCB (no soldering needed!), just supply your own screwdriver and follow our build guide.
Don't want to build this keyboard yourself? No problem, check out the fully-built version: Sinc LM
- A Stock - 0-2 minor visual defects or machining marks
- B Stock - More noticeable machining marks and/or dings on surface, but no affect on functionality
Standard Layout but ergonomic
The keys of the Quefrency LM are arranged like a normal keyboard, bringing you a familiar layout so you can adjust easily. Enhance your setup with a split board to improve ergonomics.
Hotswappable Switches
No need to learn how to solder! Just push your switches in and pop them out again if you want to change them up.
We've got a variety of great switches for you to choose from, like tactile or linear ones.
There's also silent tactile and silent linear ones as well, if you want to keep things as quiet as possible around your office.
Built to sound and feel good
The Quefrency LM sports multiple mechanisms to have an excellent, uniform sound profile and feel. First, o-rings help provide isolation between the top portion of the keyboard and the tray.
Next, a silicone tray liner helps create a deeper sound, while also serving as a way to protect the hotswap sockets from getting ripped off and damaging the board.
Finally, a layer of foam in between the switch plate and circuit board provides cushioning you'll feel with every keystroke.
