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!

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 controller should be installed further to the the right on both sides (contrary to what the silkscreen seems to suggest), i.e:

• Closer to the PCB edge in the left half
• Further from the PCB edge in the right half

In other words, the controller pins/sockets should be installed in the holes as highlighted on the back of the PCB, not the front.

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
• No diodes! There’s enough I/O on the Frood that there’s no need for a matrix (and therefore no need for diodes)
