Baikal Split Keyboard |Handwired Corne| ZMK |Ergo

The goal of this project was to create a simple, cheap, and easy-to-build handwired Corne keyboard with step-by-step instructions.

When I got into building keyboards, I wished something like this existed: a detailed guide that walks you through the entire process. This project is designed so anyone who wants to build their own handwired Corne can do it with confidence.

Key Features

• Budget-friendly: Total build cost around ~€20 (excluding keycaps and tools)
• Beginner-friendly: Ready-to-flash firmware included so no coding required if you follow the wiring diagram
