Keybytes ‘truly modular keyboard’ starts with one key and is assembled like Legos
Developer notaroomba (AKA Nathan Alspaugh) has published details of his Keybytes project on GitHub. In essence, this is a modular project where a Keyword hub is magnetically connected to Keybit keys, and each key has its own microcontroller. Hence the number of keys and their layout are entirely up to the user, with a modular design akin to building Lego.
We’ve seen oodles of imaginative and truly excellent mechanical keyboards over recent years, but Keybytes probably offers the greatest flexibility with regard to layout and key selection we’ve ever seen.
It starts with a Keyword, which is the main board that the Keybits connect to. This central component houses a stacked pair of PCBs. The top board packs an Arm Cortex M4-powered microcontroller, Bluetooth antenna, and flash memory. The lower board offers USB-C, charging, and a buck-boost converter.
Adding keys seems like a cinch. Every Keybit, one of the modular keys, contains a CH32V003 RISC-V microcontroller. …
