This 'truly modular' keyboard can be built like a Lego set — meaning you can add as many keys as you…

• Keybytes lets users assemble custom keyboards from magnetically connected individual keys
• Every Keybit contains its own RISC-V microcontroller for individual key operation
• A full-size Keybytes configuration could cost approximately $900 to assemble

MIT student Nathan Alspaugh has developed Keybytes, an open source keyboard project that lets users create custom layouts by connecting individual keys to a central controller.

The design uses magnetic connections and dedicated microcontrollers to support flexible arrangements.

Keybytes consists of two main elements: the Keyword controller and individual Keybit modules, which connect magnetically to form a personalised keyboard.

Magnetic keys allow custom layouts

Each Keybit contains a RISC-V microcontroller, allowing individual keys to operate independently rather than relying entirely on one central processor.

Every Keybit measures 19.05 x 19.05mm, corresponding to a standard 1U keyboard unit.

Its four-sided pogo pin connections carry power and I2C communications, allowing modules to connect through different edges and accommodate varied arrangements.
