The Corne Keyboard
Welcome to the Corne (previously known as the Helidox)! Originally designed by foostan in Japan, our version of this keyboard comes in 3 different variations:
- Pre-builds: Fully built, pre-flashed, requiring no soldering, with choices of switches, and with shinethrough keycaps. Ready to be used straight away!
- Barebones: Same as above, just without switches and keycaps.
- Solder Kit: Great for DIYers, requires full soldering and assembly.
All of these variations are available for both MX and Choc(V1) switches.
NOTE: Our designs are unique to us so please make sure to follow our build guides and videos.

Easy To Use
1. Plug & Play
Our R2G keyboards are sold fully assembled & preflashed. Once you recieve your keyboard you can connect it to your device and it will work straight away!
2. Change your Layout
Changing your layout has never been easier thanks to VIAL. It has a very easy to use configurator allowing you to change your key mapping with just a few clicks. It really could not be easier! More on this further down below.
3. Money Back Guarantee
We understand moving to a non-standard keyboard layout can be tricky - if you find you are struggling with the different layout or are unhappy with your keyboad in any way - don't worry! We offer a full 30 day money back guarantee. No questions asked.

Cross-device compatible
Our R2G keyboards can be used on multiple platforms including Windows, macOS, Linux, iOS, Android, and more.
1. Driverless USB HID Protocol
The keyboard speaks USB HID (Human Interface Device) - the global, standard language built into virtually every operating system. The moment you plug it in via the USB-C port, the device instantly recognizes it as a standard keyboard without needing external drivers.
2. On-Board Storage
Traditional keyboards rely on background software running on your computer to handle custom keymaps. Our keyboards saves their layouts, layers, and macros directly onto the RP2040 chip's internal flash memory.
3. Device-Agnostic Processing
Because the keyboard handles all the logic internally, it only sends standard, universally understood keystrokes to your computer or tablet. You can program your layout on a PC, unplug it, and take it to a locked-down work laptop, Mac, or iPad - your custom settings remain perfectly intact.
Easy To Customise
Vial is an open-source program used to customize mechanical keyboards in real time without needing to write code or constantly re-flash your keyboard's firmware. Think of it as the ultimate control panel for your keyboard.
Features:
- Remap Keys: Easily reconfigure keys to any other key or key combintation.
- Manage Layers: You can assign keys to act differently when a modifier (like Fn) is held down - perfect for making smaller keyboards feel full-sized.
- Create Macros: Program a single key to type out an entire email address or trigger complex shortcuts.
- Advanced QMK Features: Vial allows you to set up advanced behaviors right from the visual menu, such as Tap Dance (where tapping a key does one thing, but double-tapping or holding it does another) and Combos (pressing two keys at once fires a third input).
- Control Lighting: You can adjust your RGB lighting styles easily.
- Optional Encoder Knobs: You can setup and change what your rotary encoder knobs do.
Fully Hotswappable
On a traditional keyboard, the switches (the clicky mechanisms under the keycaps) are permanently soldered onto the circuit board. If a switch breaks or you want to try a different type, you have to melt the metal solder to get them out.
With a hotswap keyboard, special tiny sockets are pre-soldered onto the board for you.
Why hotswap is a game changer:
- Zero Technical Skill Required: You just use a simple little metal tool (a switch puller) to pop the old switch out like a Lego piece and click a new one right into place.
- Endless Customization: If you get tired of loud, clicky switches, you can swap them out for smooth, quiet ones in about 20 minutes.
- Easy Repairs: If your "W" key stops registering because the switch wore out, you don't have to throw the keyboard away or buy a new one. You just swap that single broken switch with a spare.

Per-key RGB and underglow
On a standard keyboard, lighting is just a generic, one-size-fits-all background glow. You can't control specific keys, and the lighting is purely decorative.
With Per-Key RGB and Underglow, you get two independent, highly specialised lighting systems built directly into the board.
- Visual Shortcuts: Color-code your keys by function - like making gaming keys green and hotkeys red - so you can navigate the board instantly.
- Perfect Visibility: A dedicated light sits directly under every single switch, keeping letters crisp and legible in the dark without straining your eyes.
- Total Customization: Skip the basic rainbow waves; you can program the exact color and animation of every individual button.
Optional Encoders
Each half of the keyboard has hotswappable locations for our hotswap encoder. (sold separately)
They can be positioned in multiple different locations on the keyboard, allowing you to fully customise your keyboard. (only one encoder per half)
