It belongs with the keyboards and iot & wireless designs in this gallery.

From the project

This project attempts to create easelly reproducible split ortholinear hotswap mechanical keyboard.

This project attempts to create easelly reproducible split ortholinear hotswap mechanical keyboard.

Gimmics: + This design doesn't require any diodes + Uses PiPico as MC, runs on CircuitPython + Key layouts are changed by dragging a file onto PiPicos storrage + Halves are connected through TypeC + PCB fits into 100x100mm square, so it is very cheap to order from Chineese manifacturers
