From the project

Pipar is a collection of keyboards

Pipar is a collection of different keyboards and keypads that I have designed. Each PCB in the series has unique features tailored to different needs and preferences.

The Pipar keyboards run ZMK firmware. Board definitions, custom drivers (LED indicators, caps-word events, a recovery watchdog), keymaps, and shields live in the zmk-keyboard-pipar ZMK module — included here as the zmk-keyboard-pipar submodule.
