About the Pipar flake PCB
Pipar flake is an open source PCB design by RasmusKoit, published on GitHub. It is a 2-layer board measuring 55 × 74.1 mm, with 32 components from 8 distinct parts.
By type, the board carries 10 resistors, 9 LEDs, 9 diodes, 2 switches and 1 transistor.
It belongs with the keyboards and iot & wireless designs in this gallery.
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.
