  • Add-ons *

  • 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.

  • TRRS socket is not required for wireless builds as the halves communicate via Bluetooth

Cantor Pro LP v3 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 around the Frood or nice!nano controllers instead of the Black Pills, 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.

Formerly known as the Cantor Pro Frood, it now supports nice!nano controllers for wireless operation!

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 Kailh Choc V1 low-profile switches
  • Uses Kailh Choc hotswap sockets
  • Two controller options:
    • Our powerful but affordable Frood microcontroller module (based on RP2040)
    • New in v3: use nice!nano controllers for wireless operation! Batteries can be installed in the mid-layer below the controller
  • Improved outline – the controller was moved down to reduce the empty space below it (new in v2)
  • 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)

⚠️💀 Warning: Never plug/unplug the TRRS cable while the keyboard is powered! It could damage the data pin of the controller. 💀⚠️

Kit contents

  • 2x main PCBs
  • 2x 2 mm acrylic switch plates (clear or smoky grey)
  • 2x acrylic mid plates (2 mm clear or smoky grey, or 3 mm in other colours)
  • 2x 3 mm acrylic bottom plates with brass threaded inserts installed
  • 42x Kailh Choc V1 hotswap sockets
  • 2x TRRS sockets
  • 2x reset switches
  • 8x stainless steel screws
  • 8x adhesive silicone feet

Required parts not included in the kit

Optional parts not included in the kit

  • 2 packs of controller sockets/pins (choose the “Frood” packs when using the Frood, standard when using the nice!nano) to make the controllers removable
