It belongs with the keyboards and displays & leds designs in this gallery.

From the project

modular keyboard ecosystem

etzee is an open modular input-device ecosystem. It combines keyboards, utility modules, magnetic pogo-pin connectors, local displays, haptics, and firmware that can discover and communicate across connected modules.

The project is early and hardware-heavy. The current active board is B11; M0 and M9 are planned modules.

B11 is the first primary etzee keyboard. Current design goals:
