Cantor Pro Frood 40% Diodeless Low-profile Hotswap Split Keyboard Kit

Would you like to build a small affordable low-profile keyboard, but don’t enjoy soldering diodes? Well, this might just be the kit for you!

Based on the design by Diego Palacios with help of contributors (GitHub repository). Modified by 42. Keebs to the Frood controller instead of a Black Pill, hotswap sockets, and include switch plates.

42. Keebs is sponsoring Diego on Github with a monthly donation of $25.


  • 42-key layout similar to Corne, but with more pronounced stagger
  • Uses Kailh Choc V1 low-profile switches
  • Uses Kailh Choc hotswap sockets
  • Includes FR4 switch plates
  • Based on the powerful but affordable Frood microcontroller module
  • No diodes! There’s enough I/O on the Frood that there’s no need for a matrix (which means no need for diodes)

Kit includes:

  • 2x main PCBs
  • 2x FR4 switch plates
  • 2x 2 mm clear acrylic bottom plates
  • 42x Kailh Choc V1 hotswap sockets
  • 2x TRRS sockets
  • Brass standoffs and screws
  • 8x silicone feet

Other parts required but not included in the kit:

Weight 0.1 kg
