Creators! Feel free to tip me off about your keyboard related projects to bring them to 120K readers.

After boards like the HiveMind, Vimana and Batarang, the Smile36 by Protieus(z) is a tiny keyboard inspired by Policium's Grin. (If you need a quick recap, Policium talked about the evolution of his layouts here.)

This is my first sponsored keeb by PCBWay. The Smile36, a GRIN inspired keyboard that is 40%. Policium had a 40% but I don't think it has been released as GB yet – Protieus(z).

The layout was manually drawn out in KLE by approximation. The Smile36 started out as a handwired build, and the author ran into issues with the first PCB, so the project's latest version is Rev8.


  • 36 keys, Grin layout
  • no hotswap sockets
  • Waveshare RP2040-Zero controller
  • encoder
