The Keybytes project, developed by a modder known as notaroomba, introduces a modular mechanical keyboard system based on individual building blocks. Each unit, called a Keybit, features a full-height MX mechanical switch, a dedicated PCB, and magnetic connectors. These components allow users to snap keys together to create custom layouts.
The system relies on a central motherboard, the Keyword, which houses a USB Type-C port, battery charging circuitry, and an STM32WB55 microcontroller. Each Keybit is equipped with a RISC-V CH592F microcontroller, enabling rotation-agnostic connectivity. The design supports various configurations, including in-line arrangements or offsets of 25%, 50%, and 75%.
The hardware ecosystem includes specialized PCB options, such as a version with a 3-axis Hall sensor for joystick or Hall effect switch functionality. Additionally, the project provides spacer Keybits with power passthrough in 1u, 0.75u, and 0.5u sizes. The latest revision incorporates six magnets per side on each Keybit and automatic polarity detection.
