Open-Source Tiwaz Split Keyboard Adds Thumb Joysticks for One-Handed Gaming

Developer Timo Strube released the Tiwaz split mechanical keyboard on GitHub, offering a new option for users who want to game or work with one hand. The design lets each half of the keyboard operate as an independent controller, which matters for gamers with limited mobility or those who prefer a compact setup. This open-source approach allows the community to build and modify the hardware without waiting for a commercial manufacturer.

Developer Timo Strube releases open-source split keyboard with thumb joysticks

The Tiwaz keyboard features a 76-key layout with 38 keys on each side, providing a balanced split for standard typing or gaming tasks. Each half includes two thumb joysticks that users can configure for directional input, analog stick functions, or mouse movement. This integrated design removes the need for external peripherals, keeping the workspace clean and focused.

Specifications

• Layout: 76-key split (38 keys per half)
• Controller: STM32F401 microcontroller
• Firmware: QMK with Vial configurator
• Structure: Gasket mount
• Interface: USB Type-C

Under the hood, the board uses an STM32F401 microcontroller to handle input processing and communication. The firmware runs on QMK, an open-source platform that supports extensive customization through the Vial configurator. This combination gives users full control over keymaps, macros, and lighting without needing proprietary software.

The keyboard employs a Gasket mount structure, which isolates the PCB from the case to improve typing feel and reduce noise. It connects to devices via a standard USB Type-C port, ensuring compatibility with modern computers and consoles. The entire design is available on GitHub, allowing builders to source parts and print cases themselves.

Tiwaz is available now as an open-source project, meaning there is no official retail price or limited stock to worry about. Users can download the files and start building immediately, though they must source their own components. This model lowers the barrier to entry for enthusiasts who want a specialized gaming keyboard without a high price tag.
