Know before you buy
The Corne v3.6 is a great entry point for learning to solder. Because the components are through-hole and the layout is relatively compact, it is manageable for beginners, provided you have a decent soldering iron and some patience.
This kit includes the PCB and case hardware. To finish the build, you will need to purchase your own MX or Choc switches, keycaps, and a controller (such as an RP2040). If you plan to go wireless, you will also need to source compatible batteries.
The PCB supports both switch types, but you must choose one type for the entire build. The mounting holes and stabilizers are specific to the switch footprint, so you cannot mix MX and Choc switches on the same plate.
Unlike a traditional staggered keyboard, the Corne uses a columnar layout where keys are aligned in vertical rows. This design reduces finger travel and aligns better with the natural movement of your fingers, which can significantly improve comfort during long typing sessions.
The PCB is wireless-ready with footprints for a battery and power switch, but the battery itself is not included. You will need to purchase a compatible LiPo battery separately and ensure you flash the board with ZMK firmware to enable Bluetooth functionality.
Yes, the Corne is fully compatible with QMK, VIA, and ZMK firmware. VIA is particularly user-friendly, allowing you to remap keys and create custom layers through a simple graphical interface without needing to recompile code.
