Each key is a tiny PCB with its own CH32V003 RISC-V chip and pogo pins on all four sides, held together by magnetic cases, so the keys snap together into whatever shape you like, even a triangle or a circle. A main board does Bluetooth and USB-C. It's a work in progress: the maker is still writing the firmware and building more keys.

GitHub - notaroomba/keybytes: A truly modular keyboard

Two OV9281 cameras and a tiny Rockchip RV1103 running Linux on one board. It works out depth by block matching in the chip's video engine, and it can send depth over serial to an Arduino or run on its own. The first revision had a few bugs, and the maker plans a small batch of fixed boards if enough people sign up.
