Pros

  • Design files are published as open hardware (CERN-OHL-S)
  • 4-key thumb cluster plus a 5-way tactile thumb switch
  • Per-key RGB, underglow, rotary encoder and an LCD on each half
  • Both halves use the same mirrored PCB layout, which keeps fabrication costs down

Cons

  • No ready-made retail product; you have to source parts and build it yourself
  • Depends on the STM32G4 MCU, which needed a custom QMK branch at the time of the Hackaday write-up
