Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

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.



  • 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

Designed/generated with Ergogen.
