The keyboard uses a split layout with around 76 keys, The design is meant to be customizable and DIY-friendly. It uses Kailh hot-swap sockets, which means switches can be replaced anytime without needing to desolder them. This makes it easy to experiment with different switches later. For the controller, I used the nRF52840 development board, which works well with ZMK firmware. ZMK alows the keyboard to support Bluetooth, so it can be used wirelessly. It also support customizable keymaps, layers, and other advanced keyboard features.
