Lintilla
This 42-key wireless split keyboard by Chad Transtrum is called Lintilla.
Published November 21, 2024
Chad Transtrum shared his Lintilla, a 42-key wireless split with splay, reversible PCB, featuring Choc v1 switches and XIAO BLEs.
Hi, my name is Chad Transtrum, and I created a new ergonomic split keyboard design with some innovative features I don't think I've seen on other keyboards before – Chad.
The Lintilla comes with a low-profile 3D printed "closed sandwich" case that is only 7 mm tall, yet has space for a larger than normal 502030 250mAh battery.
Specs
- 42 keys
- low-pro Choc V1, hotswap
- "relaxed" Choc spacing (halfway between Choc and MX)
- reversible PCB
- wireless-first design, 502030 250mAh batter, ZMK
The key layout is very similar to the Klor, though with a few minor tweaks. It has an aggressive pinky stagger and splayed columns.
Unlike most other 40% keyboards, it includes a quick-access function key on each half that is surprisingly easy to reach, even though it violates the "1DFU" rule. I use those keys for mute and mission control – Chad.
In addition, it doesn't require tucking the thumb to hit any of the thumb keys.
The author wasn't comfortable with the Choc spacing on for example the Totem, but also felt the keys on the MX-spaced Klor were too far apart. The result is the "relaxed" Choc spacing: Chad split the difference, and made the spacing halfway between Choc and MX.
