MIT student open-sources Keybytes, a magnetically modular keyboard project

Developer Nathan Alspaugh, known as notaroomba, has published the Keybytes project on GitHub, a keyboard system built from a central 'Keyword' hub and individual 'Keybit' keys that snap together magnetically. Each Keybit has its own CH32V003 RISC-V microcontroller and pogo pins for power and I2C connectivity, letting users build any layout they want. Alspaugh, an MIT student, says the project only started in March and recently reached a working prototype, with all design files released under an MIT license.

Hobbyist builds modular keyboard with per-key microcontrollers and Bluetooth

A maker shared an open-source project called Keybytes, a keyboard where each key is its own 1u PCB with a CH32V003 RISC-V chip, connecting via pogo pins on all four sides for power and I2C. A main board called Keyword uses an STM32WB55RGV6 for Bluetooth and USB connectivity, with magnetic cases holding the rearrangeable modules together. The design, built in KiCad and Onshape, also includes battery charging, a buck-boost converter and flash storage for key firmware.
