Púca is a numpad / macropad with exposed components on the right edge. It features hot swap sockets, a rotary encoder for volume control, an optional OLED Display and LED underglow.
There are two configurations, either as a standard numpad with a rotary encoder and two extra keys on the north edge, or as a 22 key macropad with all 1u keys and a rotary encoder. Layers are toggled with the Num Lock key, allowing you to switch between a traditional numpad, and a second navigation layer. The layer currently in use is displayed on the OLED.
Puca currently uses QMK firmware, with support for Vial too.
