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

Juho T. from Turku (aka Squalius-cephalus) published 'Silakka44, a RP2040 based column staggered split keyboard with 42 keys and encoders. The PCB uses hotswap sockets, and just like the author's previous Silli41, the design was inspired by that of the REVIUNG41 (and also the Corne keyboard this time).

The PCB supports MX style switches, 5-pin ones included.

By the way, "silakka" means Baltic herring in Finnish.


  • 42 keys (6x3+3 per half, plus rotary encoder)
  • MX, hotswap
  • reversible PCB
  • rotary encoder
  • Pi Pico (RP2040)
