Brno (CZ) based software dev Sergei Silnov aka kumekay shared the files of his Crabapplepad, which is a very slim foldable split keyboard.
My morning coffee shop visits instilled in me the desire to write down some notes, sparking the need for a mobile keyboard – Sergei.
Thanks to the low profile of the Kailh X switches, as well as the foldable construction, you can easily carry around this keyboard in your pocket. Being wireless (via Seeed XIAO nRF52840) is another good point if you're looking for a portable device.
Specs
- 42 keys ("I use Cyrillic layout too and 36 keys is not enough")
- Split. The two halves are connected with a 3d printed hinge
- Thin. Uses Kailh X switches. 2cm thick in the folded state
- Wireless. Uses Seeed Studio XIAO nRF52840 with BLE
- Foldable. The keyboard can be folded and put in a pocket
- Minimalistic. No LEDs, no RGB, no extra keys
- Apple Magic Trackpad can be magnetically attached
