    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 controllers.
    If you want the controllers to be removable, please include 2x sockets+pins, but it is not required. The controllers can be soldered directly onto the PCBs using the included standard header pins.

Cantor Pro MX 40% Diodeless Hotswap Split Keyboard Kit

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

Designed by 42. Keebs with the Frood controller and Kailh MX hotswap sockets. Inspired by the original Cantor by Diego Palacios.

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

Features

  • 42-key layout similar to Corne, but with more pronounced stagger
  • Uses standard MX switches
  • Hot-swappable using Kailh MX hotswap sockets
  • Based on the powerful but affordable Frood microcontroller module (not compatible with other controllers without the extra 5 I/O pins along the bottom edge, e.g. nice!nano)
  • 6x RGB underglow + 1 RGB indicator (or 7th underglow LED) sadly only the top 3 RGB LEDs are working due to a stupid error in the schematic 🙁
  • 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

Kit contents

  • 2x main PCBs
  • 2x 3 mm acrylic switch plates (various colours available)
  • 4x 2 mm acrylic (clear or smoky grey) or foam (dark grey) upper and lower mid plates
  • 2x 3 mm acrylic bottom plates with threaded inserts installed
  • 42x Kailh MX hotswap sockets
  • 2x TRRS sockets
  • 2x USB-C sockets (optional add-on)
  • 2x reset switches
  • 8x stainless steel screws
  • 8x silicone feet
