  • Soldering

    Select if you want us to build the kit for you. It will add 3-5 days to the order processing time.
    You need to include at least 2x Frood controller.
    If you want the controllers to be removable, please include 2x Mill Max 315 sockets/3320 pins, but it is not required. The controllers can be soldered directly onto the PCBs using the included standard header pins.

Cantor Pro Frood v2 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!

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

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

Firmware can be downloaded from our Firmware page. For flashing guide see the Frood product page.

Please note, the new version v2 has footprints for WS2812B/SK6812 RGB LED modules, but unfortunately they are wired incorrectly due to a stupid mistake in the schematic 🙁

Features:

  • 42-key layout similar to Corne, but with more pronounced stagger
  • Uses Kailh Choc V1 low-profile switches
  • Uses Kailh Choc hotswap sockets
  • Based on the powerful but affordable Frood microcontroller module
  • New version v2 has improved outline – the controller was moved down to reduce the empty space below it
  • No diodes! There’s enough I/O on the Frood that there’s no need for a matrix (and therefore no need for diodes)
  • Includes acrylic sandwich case for a compact feel and streamlined looks – just 8.8-10 mm thick (switch plate to bottom plate, depending on bottom plate thickness)

Kit includes:

  • 2x main PCBs
  • 2x 2 mm acrylic switch plates (clear or smoky grey)
  • 2x 3 mm acrylic mid plates (clear or smoky grey, custom colours available on request)
  • 2x acrylic bottom plates – 2 mm  in clear or smoky grey, 3 mm in many other colours
  • 42x Kailh Choc V1 hotswap sockets
  • 2x TRRS sockets
  • 2x reset switches
  • 8x brass standoffs, 16x stainless steel screws
  • 8x silicone feet

Other parts required but not included in the kit:

Weight 0.26 kg
