About the Pipar chip PCB

Pipar chip is an open source PCB design by RasmusKoit, published on GitHub. It is a 4-layer board measuring 68 × 61.3 mm, with 69 components from 23 distinct parts.

Other key parts include the MCP1700T-3302E/MAY, ESDR0502NMUTAG, NPM1100-QDAA-R and ISP1807-LR-RS. By type, the board carries 17 diodes, 12 LEDs, 10 resistors, 8 capacitors, 4 ICs and 2 connectors.

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.
