Silakka54 Split Ergonomic Keyboard — ZMK, Hot-Swappable Shaft Body, NanoV2 Controller, Bluetooth 5.0 & Type-C, OLED

Connectivity: Dual-mode connection with Bluetooth 5.0 and wired Type-C. In Bluetooth mode the Silakka54 can pair with up to 3 devices (computer, tablet, phone) and switch between them instantly using a shortcut key. Wired mode provides high-speed data transmission and emergency charging when needed. Controller & customization: Uses the NanoV2 as the main controller and supports ZMK Studio for Bluetooth keymap customization. Firmware is ZMK open-source, and the board offers a hot swappable shaft body plus screen extension for flexible modifications. Display & feedback: A low-power OLED shows real-time status at a glance — current connection mode (Bluetooth/wired), battery level, active layer, connected device name, and other key information without opening a computer or phone. Ergonomics & comfort: The split ergonomic layout is designed to relieve pressure on shoulders, neck, and wrists, reducing the risk of occupational injuries and improving long-term typing comfort. Product concept: Silakka54 is positioned as an input solution centered on user needs — addressing comfort with ergonomic design, personalization with ZMK and hot-plug capability, and situational demands with dual-mode battery and connection options. Whether you’re an efficiency-focused office user or a custom keyboard enthusiast, Silakka54 delivers a tailored, comfortable input experience.
