From the project

Sköldpad 1.0 - a columnar-staggered split keyboard built with ergogen and KiCad

A split, columnar-staggered keyboard built around a nice!nano MCU with a rotary encoder, laid out with ergogen and routed in KiCad. It's based on/inspired by josukey (MIT licensed), an ergogen-based Corne clone.

Firmware (ZMK, with a custom keymap tuned for Swedish input and coding symbols) lives in its own repo: martisak/zmk-config.

The layout lives in ergogen/config.yaml.
