The Chocofly keyboard

The Chocofly is an ergonomic monosplit keyboard with 4x6 column staggered keys, 4 thumb keys and 2 additional inner keys for the index finger (60 keys total) plus one rotary encoder.

The main idea of the Chocofly is to be thin and suitable for "sonshi"-style usage (putting it ontop the laptop keyboard). It is also pretty minimalistic - no LEDs/OLEDs/labels on keycaps/wires... and in my build it even has no case. It's just a pcb with switches on top of it and small silicone legs on the bottom. And this setup works pefectly! Well, for me at least.

Notable features:

• Kailh Choc V1 switches support (both hotswap and non-hotswap - in one PCB).
• Non-agressive column stagger with just a little bit fan-angled 5th and 6th columns.
• Fancy-shmancy "flying" design.

Build instructions

A few tips specific to the Chocofly:

• You have to make the bottom of the keyboad as flat as possible. Because you will need to glue rubber sheet on it. That is why you better
  • cut the switches' legs before soldering. Insert the switch into its place, cut the legs to the optimal length, then solder them.
  • do not cut the central plastic shafts of the switches!
  • use SMD diodes instead of throgh-hole ones.
• Using 2mm think PCB should be a better option than 1.6mm, because it will hide the switches' shafts too.

Firmware

• Notes about the default keyboard layout.
• ZMK for wireless builds.
• QMK for wired builds.
